any chance you can try this with a 2.6-era kernel, say Fedora-Core-2-test1? thanks, -Len
Is ACPI enabled or disabled in the BIOS? (shouldn't panic in either case, but could be a clue) If this still happens with a recent kernel, can you attach the output from acpidmp, avaible in pmtools here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/ otherwise, please close this bug. thanks, -Len
Works fine with FC2test3/2.6.5-1.327. Thanks.
