Hi,
The git-acpi.patch replaces earlier "if(!handler) return -EINVAL" by
"BUG_ON(!handler)". This locks my machine early at boot with a message
along the lines of (It's hand copied):
Int 6: cr2: 00000000 eip: c0570e05 flags: 00010046 cs: 60
stack: c054ffac c011db2b c04936d0 c054ff68 c054ffc0 c054fff4 c057da2c
Reverting the change as follows, allows booting:
Any ideas to debug this further?
Regards,
Frederik
