I am using kernel 2.6.14 without preemptive support and Ben USB sleep
patch. Here is mi cpuinfo
processor : 0
cpu : 7447/7457, altivec supported
clock : 765MHz
revision : 0.1 (pvr 8002 0101)
bogomips : 508.92
machine : PowerBook5,2
motherboard : PowerBook5,2 MacRISC3 Power Macintosh
detected as : 287 (PowerBook G4 15")
pmac flags : 0000001b
L2 cache : 512K unified
memory : 512MB
pmac-generation : NewWorld
I am using Debian/Unstable, and when I put mi PB to sleep (closing the
lid) I recieved a crash that appears to be something releated to the
video system (Radeon).
Later I will post the information that shows Linux kernel when it crashes.
It crashes when I try to resume from the sleep.
Regards
Federico
