Your system encountered a serious kernel problem 9.10

[uknowho008]

Hi, I keep getting this error after running my computer for a while. I have never had this problem until installing the new 9.10 has this been happening to anybody else? Anybody know what the problem is? Or need more information? The only thing that I've noticed it effecting is that internet stops working and restarting networking doesn't help. Thanks.

Your system encountered a serious kernel problem.

Your system might become unstable now and might need to be restarted.

You can help the developers to fix the problem by reporting it.

I've seen this a few times when my USB disk is misbehaving. I'm pretty sure that box appears whenever the Linux kernel reports an error. Unfortunately, it doesn't actually show the error (which is irritating), nor is it enough for a bug report by itself (which isn't very helpful).

Since you also mention that networking stops working at the same time here's what I think is happening:

1) Something happens involving your networking driver and/or hardware. This causes two things to happen:
2a) You lose networking.
2b) That error message appears.

It sounds like this is a bug. Unfortunately, just clicking "report" won't give enough information to give a good bug report.

So, here are the questions to answer:

1) How exactly do you connect to the Internet? e.g.: "Ethernet cable + DSL" or "Cable + WiFi Router + WiFi laptop"

2) What kind of networking device does your computer use? Also, post the output of "lspci."

3) If you search Launchpad for the name of your networking device, can you find a bug report similar to your problem?

Good luck.

I'm connected through Netgear GA311 gigabit pci card, which I haven't had problems with before 9.10. This connects to a router which connects obviously to my cable modem.

And I don't see any similar posts on launchpad that have anything to do with my network card, but I do see a similar post about the "serious kernel problem" which doesn't help me.

Any ideas? Thanks.

[uknowho008]

It seems to be happening for frequently now, like every 15 min or so I haven to restart.

[wildweathel]

Yeah, that's interesting. lspci says you have a Realtek RTL-8169, which is the name of the chip on the card.

Searching for r8169 gives 102 bugs as of writing. To narrow this down, it'd be great to find the error message. It might be somewhere in /var/log/messages; immediately after it happens it'll be at the end. Could you especially look for a line mentioning "NETDEV WATCHDOG"?

Also, What did you run before Karmic? The pop-up error notification is a new feature in Karmic, before then networking would stop working silently. The error message was there, it just wasn't being popped-up. A lot of the bugs I'm looking at are from Intrepid and Jaunty-era kernels.

Bug #378907

You've made sure you have all the latest updates, right? I was getting the same thing until around Wednesday or so.. shortly before final release it simply stopped happening. <fingers crossed>

[uknowho008]

Oh wow! You said I had a RTL-8169 so I looked and realized that I had my cable plugged into the onboard network adapter rather than the pci card I had bought. I switched it over and see if the problem persists. I do remember my connection dropping randomly in the past and I think that's why I put a new card in in the first place. I've just never seen the "kernel problem" notification thing, which you said was a new thing.

So I'll try this with the new card and see if it continues. Thanks a lot, and good eyes.

Edit:Also, I was running 9.04 before and my current 9.10 install is totally up to date.

[wildweathel]

Lol, not good enough eyes. If I had better eyes, I'd have asked if you meant the Realtek or the VIA. From the picture on Netgear's website, it looks like the Realtek chip is on their card (the Realtek crab is visible in their product picture).

That means you're now switching from the VIA (onboard) to Realtek (expansion card). Here's hoping it works. Like I said, the Realtek-related bugs seemed to apply to Intrepid/Jaunty but are fixed in Karmic. Good luck!

haha, figures. Well so far so good. I guess this ones solved. Thanks again.

I'm enchanted to know all that.
first time I saw it I forced an fsck and rebooted, nothing to report.
