Description of problem:
I have a dual core AMD64 and occasionaly when I boot it, maybe once a week, the boot process hangs at the line "Initializing hardware"
It then prints "Disabling IRQ 225"
and then, after something like 30 seconds it again prints
kernel panic - not syncing: bad locking
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Happens occasionally during boot
is there any call trace along with that panic ?
No, that's all there is. It just stops )-:
do you have the word 'quiet' on your boot command line ? If so, remove that, and
it should print something more informational.
(You'll get a ton of other messages too, but hopefully the useful ones will be
onscreen just before the hang)
No, I don't have the quiet parameter, the kernel just fails to panic properly
)-: I do realise there isn't much to go on here...
