Kernels 3.2 and 3.4 work fine but not 3.5. Get this:

Kernel panic - not syncing: Fatal exception in interrupt

Any ideas?

Thanks!

I386 12.10 Alpha 2 working just fine on a Dell Inspiron 1012 Mini Net Book, Just FYI. No Kernel Modifications were made on that particular PC.

Thanks, and very interesting... but I do think that the 1012 has many different elements to it over my 10n. Is yours a Poulsbo chip set type?

Any ideas as to what I should try to see what the issue is?

Same here fjgaude...
We should open a bug report .. btw I believe in kernel 3.5 there is some conflict between gma500_gfx and the acpi brightness support.

Did you guys ever submit a bug report? I'm having the same problem :(

Had kernel panic as well on AMD64.
When I clicked on to submitt bug it stated one already existed.
I went and installed rc5 kernel and have not had kernel panic for over 24 hour period :p

I'm not familiar with Dell mini-10
Could you do a

cat /proc/cpuinfo

and post the results?

I've a Acer Aspire 1 netbook in the other room running without panic (so far) I'll post its results when I fire it up.

Thanks,

There is a new kernel in proposed. See sticky.

I've been getting kernel panics on my amd64x2 box since 3.5.0-1 hit the repos , both the not sync'ing and one about can't handle null pointer exception , has not occured yet on my box when running G-S , only unity .

edit : spoke too soon chrome just precipitated a kernel panic while running G-S , when I tried to go to the bbc world news site .

3.5.0-3 just hit the main repos in my update today. Rebooted and running fine.

Not familiar with Dell mini-10. This is an Acer Aspire 1 10" netbook $250 at WallMart, 15.5" external monitor TV, wireless keyboard & mouse. Nice.

Biggest trouble has been "No" automatic connection to wireless WPA network without a lot of slow manual going through systems settings netowrk on most boots: Intel Corporation Centrino Wireless-N 1000

Just did today's 3.5.0-3 No panic.

It's a dual processor cat /proc/cpuinfo for one of them:

What's the cat/proc/cpuinfo for the Dell mini 10?

Jerry, I posted the cpuinfo in #10 of this thread. The 10" Dell works perfectly with 12.04.

Thanks, fjgaude, looks very similar to this netbook
Intel(R) Atom(TM) CPU N455 @ 1.66GHz dual processor too.

I'm doing O.K. with 3.5.0-3 except for very difficult to connect wireless WPA security, launchpad and upstream buges entered.

I still get kernel panic with 3.5.0-3 when using the daily onto a USB flash. I'm good with 3.4 and earlier. I'll just wait it out, day-by-day. <smile>

@fjgaude

https://bitbucket.org/vincentliu/fc17-kernel-with-gma500-patches

" These are kernel sources for Fedora Core 17 (3.4+) with gma500_gfx patches for Linux-3.5"

these should fix our issues with kernel 3.5 and gma500_gfx, don't know if they will be included upstream in 3.5 release or not.

@all
This issue is related only to Intel Atom Gma500.

Atom N455 and other chipset are really different so don't suffer of this issue.

Thanks, Luca, for the tip. I'll just wait it out until Ubuntu 12.10 works, after all, 12.04 works just fine, better than anything so far. Not much interest until features are added over 12.04 to be excited. <smile>

@htbw
different issue.. your ati radeon card has difficult to catch lcd panel edid.. edid is the "registry" of panel resolutions. open a bug report for this, it is a problem with radeon driver.
try also to upgrade bios.. sometimes edid is fixed that way.

here instead there is an issue with intel gma500 driver about panel brightness support via acpi.

I also had kernel panics with all the versions of kernel 3.5 that I have tried, (3.4 is working fine) on my ACER 751H .
But fortunately the latest version 3.5.0.6 works without problem.

fjgaude
July 25th, 2012, 02:53 PM
Yep, the last update, really ISO Alpha 3, did it. My Dell mini works like a charm. I'm sure Luca's machine does also. Even the brightness control works, wi-fi, etc. Thanks to Alan Cox and all the developers that have made this possible, gma500 lives!

going to try.. tnx for heads up.
we can also try to use "modesetting" instead of fbdev.. i'll let u know ;)

fjgaude
July 28th, 2012, 08:37 PM
Latest kernel update, 3.5.0-6, speeds the machine up, from about 40sec to 32sec, using gtkperf... that's a significant percentage.

On my main box, Intel i5-2405S, it went from 4.2 to 2.67sec. Now what goes on here with this updated kernel?

On either machine Suspend works but will not Resume.

Are you able to resume after suspend?

In my case it works without problems (Acer Aspire one 751h)
It s first time since ... long time ago ...

arg... even tried yet.. I use the netbook just in the spare time.
I still have to try:

* suspend and resume
* brightness hotkeys
* "modesetting" as driver in /etc/X11/xorg.conf (http://pastebin.com/909sKXSU) ... it should work better than fbdev

fjgaude

With latest updates still will not resume... all else seems fine and has good speed.

I'm back to my updated precise and the 3.4.0-5 kernel , 2 day old daily install wouldn't boot to dt without kernel panic and todays zsync'd amd64 wouldn't complete an install without panicking . oh well theres always 13.04 :lolflag:

My main box, notice signature, works perfectly with 12.10 latest updates. No issues, even resumes. But it's a different issue with the 32-bit Poulsbo Dell mini-10.

ok.. tried modesetting as X driver.

You need to enable proposed repository, in order to upgrade to Xorg 1.13, and then install xserver-xorg-video-modesetting package.
At next reboot the brand new modesetting driver is enabled and loaded by default.. It is snappier than fbdev. Unfortunately no Vaapi and OpenGL extensions but who knows in the future.

Btw I've enabled GPU-rendering in Chromium and I get a smooth scrolling... also Kde 4.9 is really fast :)

Thanks, Luca, for showing the way.

lucazade
August 8th, 2012, 07:57 PM
further analisys:

* to get brightness hotkeys working on my acer I have to pass a parameter to kernel:

acpi_backlight=vendor

* to get suspend working I have to remove default quirks database from suspend pm-utils

sudo mv /usr/lib/pm-utils/sleep.d/99video /usr/lib/pm-utils/99video


* using "modesetting" X driver glxgears goes up to 115fps (95 with fbdev)

* with "modesetting" external video output works correctly (tried with VGA, probably the same with HDMI)

* cpu usage seems lighter, probably because modesetting employs EXA as backend.

a step forward in the right direction, there is no need to do other tricks like in the past :)
