panic on booting
I have a HP 2140 netbook. I use the ubuntu netbook remix distribution, version jaunty from 29.3.2008 https://wiki.ubuntu.com/UNR
On booting, it issues a kernel panic. I have the feeling, that it is related to the DC power plug. If it is plugged in, the panic always happens, if not, only somtimes. Attached is a screenshot.

Will you please add the boot option of "nolapic_timer" and see whether the issue still exists?
Will you please boot the system with ACPI disabled(by adding the option of "acpi=off" ) and attach the output of acpidump, lspci -vxxx?
Adding "nolapic_timer" made it worse, it then always panics.
I'll try the rest later and provide you with the acpi outputs...

acpidump for hp 2140 netbook
Created attachment 20770 [details]
lspci -vxxx for hp 2140 netbook
those both acpi dumps were made with the boot option acpi=off
Will you please boot the system with battery and attach the output of dmesg?
Will you please also try the previous kernel and see whether the box can be booted?(For example: 2.6.27/28)
Will you please try the following boot option and see whether the box can be booted?
b. processor.max_cstate=1 (The processor should be compiled as built-in module).
If it can be booted, please attach the output of dmesg.
idle=poll and the problem persists/can't boot at all
and processor.max_cstate=1 is the same
As I told in the ticket, it's a 2.6.28 kernel from ubuntu jaunty (for the netbook remix). I can try 2.6.29.
please try a latest kernel, like 2.6.29.
finally, i managed to compile 18.104.22.168, configured with (more or less) the same config file as ubuntu's.
booting with DC power plugged worked, and acpi is loaded and shows battery status, temperature, etc. in /proc/acpi
so, it is either a configuration problem with the old kernel (that was silently fixed when importing those settings) or it is fixed in 22.214.171.124.
what's not working now is wlan, but that's another topic ;)
