I have an Acer Aspire 5315 laptop, Intel GMA965 chipset, with Debian Testing installed. Today morning I've made an system upgrade. Since then, when kernel 2.6.32-trunk-686 is loaded, the laptop is powering offÂ* suddenly, few minutes after boot. If I choose the old kernel the symptom do not happens. Is any bug or there are some config to do?
In time: another machine, a desktop, with the same distro, was upgraded too and didn't show any problem with the new kernel.
Best regards,

| pentium pc...
Same here with both Debian and vanilla versions of all 2.6.32 kernels,
home-compiled, running sid on an old IBM Thinkpad A31, with cpufreqd
and cpufrequtils. On my machine, the shutdown is caused by runaway
overheating after only a few minutes, so there's not much time for
diagnosing. 2.6.31.6 with same basic .config runs fine.
Nothing amiss that I can spot in syslog, dmesg or lsmod. ACPI shows
fan running. Powertop shows unceasing and repeated instances of
"flush-254" attributed to "bdi_writeback_task." I googled those
messages, but couldn't find anything helpful.

I had the same symptom long ago on a change of kernel (don't remember which
one). I solved the problem doing a bios upgrade.(Acer aspire 5712Z)

Dear John, you was right.
After investigating I found that the ACPI subsystem isn't measuring CPU temperature. The command 'cat /proc/acpi/thermal_zone/TZ01/temperature' returns zero celsius degrees when the new kernel is loaded, so the fan never runs. This is why the symptom doesn't happen on the old desktop machine, which don't have fan control. By while, I removed the new kernel and I'm using the old kernel, which reads the real temperature and controls the fan correctly, and I will wait for a new kernel update to see if the bug was fixed.
