JMicron PATA problems

[lazerradial2003]

For people having problems, i found the following to help:

anyone getting error 21 or similar from grub after installing, its worth using lilo instead (this can be done by installing form the alternative install CD, if anyone wants more details i can give them). Also if anyone has any updates on whether Grub is supporting Jmicron IDE / SATA then i'd be very interested!

The "Error allocating resource to PCI:xxxx" error repeated several times (sorry thats not the exact message im doing it from memory) was solved for me by disabling USB mouse support in the BIOS (possibly USB legacy support in some BIOS's).

Another option is disabling IOAPIC in the BIOS, this may well help but beware only one core will be detected so this is a bit of a zero option.

It's also worth downloading the latest alternate install CD daily of Edgy, some worked for me some didnt.

IT took me weeks to get a stable Edgy install running on my dual core box and i can't remember all the steps off the top of my head but i'll be happy to try and answer any questions...

After you manage to get Dapper/Edgy installed, put pata_jmicron on the blacklist.

$ sudo gedit /etc/modprobe.d/blacklist-pata

add "blacklist pata_jmicron" to the end and reboot.

This will make it stop loading the primitive JMicron driver and use the more advanced libata one instead. This one has many less bugs in it. Make sure libata has support for JMicron in your kernel before doing this. Enable DMA so you don't get freezing during I/O.

$ sudo hdparm -d1 /dev/hde
$ sudo hdparm -d1 /dev/hdf

(etc, etc...)

I'm using my kernel here: http://www.ubuntuforums.org/showthread.php?t=326343

It seems to work great. I had a few problems before I blacklisted pata_jmicron, however. Now all I'm getting is this, and I'm trying to debug it:

[65028.757253] hdf: cdrom_pc_intr: The drive appears confused (ireason = 0x01). Trying to recover by ending request.
[65065.710222] hde: cdrom_pc_intr: The drive appears confused (ireason = 0x01). Trying to recover by ending request.

And this:

[ 43.540410] device-mapper: table: 253:0: linear: dm-linear: Device lookup failed
[ 43.540416] device-mapper: ioctl: error adding target to table

Where do you get the daily Edgy CD? All I see is Feisty Fawn and the install in that is broken for me.

I would say that I would better spend my time learning to program the system than living with its hardware incompatibilities.

This may be a workaround. However, scores of people cannot install Ubuntu in the first place. So, for the time being, it's advisable to stay away from the Intel 965-based boards (or go full-SATA).

I have finally managed to install Ubuntu. I had to buy a new SATA-harddrive, but it installed nicely from my PATA dvd-rom. Both the LiveCD and the Alternate-install-cd worked fine, and both the 32 bit and the 64 bit installed fine.

Feisty on the other hand hanged, but that is to be expected from beta media I guess.

I don't know about all this modification for a problem a couple of other distro's (Mandriva 2007, and Zenwalk 4.2) have solved with no user input/modifications whatsoever. It's sad but the kernel in Zenwalk 4.2 is 2.6.18 and it installs without a hitch on my Intel 965 Gigabyte w/jmicron. I tried the Ubuntu 6.10 and the latest and greatest Fiesty with kernel 2.6.20 no dice. I even went to the trouble of buying the Lite-On Corp CD-RW/DVD Model SHC-S257K0SC SATA Drive Ubuntu still won't install that I know of without some exotic pre-kernel commands that I don't have a week to spend trying to figure out. No gentlemen i'm sure that this problem will be solved but for now i'll have to wait for the final Fiesty edition. I will be using Zenwalk on my most powerful system and of course Ubuntu on my older compatible systems. Ubuntu does rule, and maybe they are doing the right thing in getting the problem solved at their speed, but a few of us have these Intel 965 boards and can't use it for now.

with SUSE 10.1 Kernel 2.6.16 I have the same problems....at installation NO CDROM

This is causing some anxiety! Not only Mandriva and ZenWalk install without a problem, FC6 also knows how to deal with the JMicron stuff on board.

What's going on? Why is Ubuntu not capable of doing this? When Edgy was lauched, they (launchpad) said it would be solved in 2.6.18. Now, Feisty is on 2.6.20 and still no-go? I really hope this is not true....

Hi my friend,

I own a P5B DLX with the JMicron Controller and i'm not beeing able to boot [K]Ubuntu, error 21 freezes the PC during the BOOT.

Can you provide some more information about LILO Installation/Configuration process?

I really appreciate that!

Regards,
