v2.6.26: Bad EIP value at shutdown

v2.6.26: Bad EIP value at shutdown

[Vegard Nossum]

Hi,

My apologies for the bad report, I just got this when shutting down a
v2.6.26, and with no camera at hand, I wrote down what I could see:

The last line of the stack dump contained the number 0xfee1dead, which
I assume is some kind of magic number.

The stacktrace:

notifier_call_chain
_cpu_down
disable_nonboot_cpus
acpi_clear_gpe_block
kernel_power_off
sys_reboot

Code: Bad EIP value

So a NULL-pointer call.

./linux/reboot.h:#define        LINUX_REBOOT_MAGIC1     0xfee1dead

Not especially helpful info given that stacktrace.
