Subject: kernel bug report 2.6.24-rc8 on core2quad q6600 with debian unstable
 amd64

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Hi folks, I'm sending the bug report here, since i have no idea where
else to send it. I hope it is helping.


[1.] One line summary of the problem:
The kernel panics under high CPU/IO load, compilers segfault, mdadm
used to do so, too.

[2.] Full description of the problem/report:
I upgraded my system to fairly new hardware and find myself unable to
compile any kernel source and the system panics under high load e.g.
resyncing a RAID or building a kernel. Building kernel is 100% sure to
result in a kernel panic.

[3.] Keywords (i.e., modules, networking, kernel):
kernel, panic, gcc, load, high, high load

[4.] Kernel information
[4.1.] Kernel version (from /proc/version):
Linux version 2.6.24-rc8-wintix (root@...gstation) (gcc version 4.2.3
20080114 (prerelease) (Debian 4.2.2-7)) #1 SMP Tue Jan 22 21:17:40 CET
2008

[4.2.] Kernel .config file:
http://linuxdingsda.de/~wintix/temp/config.gz

[5.] Most recent kernel version which did not have the bug:
I tried 2.6.23 but doesn't work there, too

[6.] Output of Oops.. message (if applicable) with symbolic
information resolved (see Documentation/oops-tracing.txt)
# make-kpkg kernel_image --initrd

drivers/acpi/pci_bind.c: In function 'acpi_pci_unbind':<built-in>:0:
internal compiler error: Segmentation fault
Depending on which kernel i build, it fails on different things.

[7.] A small shell script or example program which triggers the
problem (if possible)
See 6.

I tried disabling HPET and VT in the BIOS but that didn't help. I also
ruled out any memory problems with memtest86+.Don't know what else to do.

Please let me know if you need any additional information or need
