Hi,
Last 29th june I upgraded kernel to 2.6.37.6-0.20 on opensuse 11.4
As usual, I reboot after upgrading process finished, but grub freezed at the beggining. I tried to boot with failsafe desktop option and system boot successfully.
I have searched In the boot log file what could be the problem and I have found an infinite loop with this message:
BUG: unable to handle kernel NULL pointer dereference at 000000000000004c
Below I attached the last lines of the log file.
Any help would be appreciated.
Thanks in advance.
Fernando
