log out because of "clocksource unstable" (tsc)

[turbooster]

I hope this isn't a duplicate of Bug #273313:

I upgraded from Intrepid to Jaunty and now every hour or so my PC (DELL Vostro 1000 w/ Turion 64) logs out. dmesg says:
"Clocksource tsc unstable (delta = -301051707 ns)"
I read that it is possible to add 'notsc' to kernel line (did so but I haven't rebooted yet. Anyway it worked before and should work by default).
I didn't notice a longer boot time as mentioned in Bug #261794 or Bug #190414

Will report if notsc changed anything. And will try clocksource=... shenanigans then.
Setting the governor to performance is not an option. It's a laptop after all...

cat /sys/devices/system/clocksource/clocksource0/current_clocksource
acpi_pm

cat /sys/devices/system/clocksource/clocksource0/available_clocksource
acpi_pm jiffies tsc

What Information do you guys need?

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information. Please run the command

apport-collect -p linux 364825

to automatically attach needed information.

For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeamBugPolicies Thanks in advance!

I tried to do just that but granted read-only rights only. How to revert that? I tried purging apport-collect and reinstalling it.
Is there some kind of cache I can delete? Didn't find in /var/cache

See in ~/.cache/apport/launchpad.credentials

I don't think this command actually works the way one might expect. You
need to run:

apport-collect -p linux-image-`uname -r` NNNNNN

in order for the kernel's apport hook to be run. The documentation (which
is actually at https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies) is
incorrect in this regard and needs to be fixed.

You were right I guess ;)

[turbooster (comacritter)]

update:
My "/sys/devices/system/clocksource/clocksource0/current_clocksource" is now hpet and the error seems to be gone.
I tried tsc as well but everything went SloMo from there (litterally: All the GNOME menus faded in at half the usual speed and after a minute or so the computer would hang and only REISUB and K worked ).
I have still got "APIC error on CPU0: 40(40)" in my syslog, but that's due to a bug in the BIOS I guess (see http://ubuntuforums.org/showthread.php?t=671780)
Was hpet the default in Intrepid? It was only after upgrading that this "error" ocurred.

update #2:
the error is NOT gone with hpet. Still logging out every now and then.

[turbooster (comacritter)]

i didn't have a logout since a week or so. Closed although APIC error still exists.

Closing per the last comment.
