Looks like bug #593650 may be related to this this. I've install linux-

believe) I have the same issue on my thinkpad x31.
The funny thing is that the freezes occurs more frequently on some users

With a new user, I hardly happens and on my mostly used user, it is
really frequent!
--
Near as I was able to figure out (prior to 10.04) the issue appeared to
center around wireless usage. The more wireless usage a user had the
more likely they were to trigger the bug/issue.
However, that being said, since my upgrade to 10.04 my hardlocks have
been replaced with random reboots.
Update - I crash even chrome is not running (nightly download of
torrents, firefox etc.) so I guess this is wifi related in my case as
well

kernel oops. From
I've got a more linux savvy friend who told me that Ubuntu doesn't load the
package for getting an oops by default. I haven't looked into it further,
but if this is true, then it would explain the lack of an oops.
Tell me what to type at a shell prompt and I'll tell you about the IRQ.

i've noticed similar hardware lockups, but it usually happens when i'm
running virtualbox, i just installed a big batch of updates, including
kernel updates, and i can't figure out which update caused this problem

I'm also having this problem. It seems to only happens on some wireless
routers.
I have a Lenovo W500 with an Intel 5100.
The lock-ups / kernel panics only happen when I'm using the iwlagn
driver.
Other than a serial console is there some way to find out what caused a
kernel panic?

Seems I spoke too soon. Just had another lockup this morning.

I tried a bunch of different configurations. still using iwlwifi.5000
can't remember the rest of it at the moment I'm doing some cadd work so I'm
in windows atm. its the 5000 chip set series loader for iwlagn.
at any rate I installed ubuntu 8.10 32bit with great success many fewer
issues.
Not sure which of the changes did it, but so far my laptop has gone the
entire weekend without a kernel panic, which since upgrading to 8.10 is
something of an achievement.
The changes I've made:
- currently using the ath5k module
- upgraded to the linux-backports-modules-intrepid package
I think that this is a version issue with iwglan
