I encountered this bug on my silver PowerMac G4:
cat /proc/cpuinfo [...] machine : PowerMac3,5 motherboard : PowerMac3,5 MacRISC2 MacRISC Power Macintosh detected as : 69 (PowerMac G4 Silver) [...]
cat /dev/sndstat [...] Card config: PowerMac Tumbler (Dev 21) Sub-frame 0 Audio devices: 0: PowerMac Tumbler [...]
I am currently using the normal Ubuntu 7.10 kernel (linux 2.6.22), without PREEMPT, and using CONFIG_HZ=250. I also had this problem on Ubuntu 7.04 with kernel 2.6.20. I did _not_ have this problem on Ubuntu 6.10 with kernel 2.6.17 !
