Created attachment 25363 [details] acpidump-ascii.txt dmesg.txt lshw.txt lsmod.txt lspci.txt On FS AMILO PRO V2055, kernel freezes rarely, about 5-15 minutes after booting. Google gives lots of search results about this problem but none of them solved this issue. I checked my BIOS version and it is the most recent. Trying kernel with parms 'noacpi', 'acpi=off', 'pci=noacpi', 'noapic', 'nolapic' did not help becouse this way Debian did not find the HDD. When kernel freezes, there is no kernel panic nor other evaluable error message. Using an other Amilo Pro V2055 notebook, the error also occurs so I don't think it is a hardware error. My kernel is installed from the original Debian SID dist pool: $ uname -a Linux zsbook 2.6.32-2-686 #1 SMP Thu Feb 11 04:08:42 UTC 2010 i686 GNU/Linux

Not a bug. Sorry. CPU was overheated.
After some hours testing, without CPU overheat the error still persists.
please try boot option 1. maxcpus=1 2. idle=halt to see if the problem still exists. BTW: why do you think this is an ACPI problem? :p
Thank you, with these boot options I have more time after booting, the first freeze appears about in 1-2 hours. I guess ACPI or PCI/APIC problem becouse after I visited Google results, everyone who has similar problem (sudden freeze on BIOS-buggy FS Amilo Pro notebook, without kernel panic etc) solved it with disabling ACPI and/or pci apic. So I'm not sure this problem is ACPI-related, I just always ask Google before I address a question or report a bug :) Meantime, I've compiled a preemtive kernel without io-apic, I give a try with that.

Definetly not a kernel bug. With driver debugging, in commandline mode, I noticed serious hardware errors. It looks like every controller (USB, SATA, all other peripheals) disconnects when this 'freeze' occurs. The most annoying with this is that the other Amilo Pro V2055 notebook produces the same symptom, however this IS a hardware bug. So conclusion is this notebook series should not be used. Thank you for the effort and sorry for bothering with false-alarm.
