can you try newer 2.6.39-rcX from experimental, is it fixed there?

Please test whether any of these kernel parameters help (one at a time):

clocksource=jiffies
clocksource=pit
idle=halt

Could you also send a log from an earlier kernel version where this
problem does not occur?

Ben.

Done (RC6). No. :-(

did it ever work?
if yes please how correct boot dmesg of the working linux-2.6.
if no please report upstream to the brltty upstream.

thanks

Max, brltty is a userland component. I think this has to be a kernel
bug (or a BIOS bug that the kernel has to work around).

Except for the kernel reporting on the fact that the pit clocksource was registered explicitly rather than chosen, nothing happens. (Interestingly, "tsc" fixed it in a previous encounter with this problem, where acpi_pm was default in Linux 2.6.18, on the same hardware, but with less drastic results, and is the one chosen now. Trying acpi_pm again just in case, as that was also a candidate, and it already seems more stable.)

I'll let you know when I locate it.

You already have the later kernel log; here are the earlier log, the precise ntpd from that time, and the not-so-precise ntpd from today using the same clocksource.

Default Bug#626427: linux-image-2.6.38-2-686: Horrible Time Skew, Eventual Near-zero Responsiveness

I agree that this seems to be a regression in acpi_pm since Linux
2.6.32.

Please report this bug upstream at <https://bugzilla.kernel.org> under
product 'ACPI', component 'Other'. Include the information you've sent
here - the logs from 2.6.32 and from 2.6.39-rc6, and the possible
connection with brltty. Let us know the bug number or URL so we can
track it.

Ben.

Once a job is fouled up, anything done to improve it makes it worse.

OK, done. Bug 35772 at:
https://bugzilla.kernel.org/show_bug.cgi?id=35772

My braille display is away for repair; I won't be able to get more information until it returns. Sorry for delays.

Cheers,
Sabahattin
