Bug#467227: [powerpc] oops when resume
Package: linux-image-2.6.22-3-powerpc
Version: 2.6.22-6
Severity: important
Hi all,
whenever I switch on my powermac and wait until the machine suspend (because it on battery and pbbuttonsd has been instructed to suspend it; or because my battery went to 0%), then I press a key to resume the machine, but I get this Oops:
