When you have a second box around you could
(see /usr/src/linux/Documentation/netconsole*) and see if that
catches an oops. Or use a serial console.
I will try a netconsole. A serial
console is not an option since I have no
serial port on this laptop. Please correct me if I am wrong, but even with a
USB/serial adapter, there is too much USB stack in the way to configure a USB
That's correct. There is EHCI debug port for USB, but the drivers
for that are not currently included and it needs a hard to get and e
firescope (console over firewire) can be also used as an
cheap alternative, but let's try netconsole first.
Last night I installed kernel-default-188.8.131.52-7 from Factory (as well as all
the updated packages.) This kernel ran about 30 minutes before a lockup.
I then added "irqpoll" and tried again. This time the -default kernel ran
for 5.5 hours until I shut it down.
Ok that narrows it down somewhat.
This morning I tried again without irqpoll and once
again had a lockup after
about 30 minutes. I am currently running with irqpoll again and will see if
it runs all day without a lockup.
Assuming irqpoll works around the issue, why does a -vanilla kernel work
without irqpoll but -default needs irqpoll? (I have already considered
Hmm, that would point to that one of the patches included in the
suse kernel is to blame.
Possible culprits are libata and ACPI and possibly alsa I would say.
One way to track it down would be to build custom kernels
with these patch blocks removed and see which one helps.
Would be somewhat time consuming though
Having some kind of console output would narrow it down.
