Linux kernel 3.x problems on PowerMac G5

[Phileas Fogg]

Hi,

recently i got a PowerMac G5 and installed Debian Linux 2.6.32 on it.
Everything works so far and Debian boots properly.

Today i tried to boot Linux 3 on the machine and it doesn't boot.
The Linux 3 kernel was cross-compiled by me.

On Linux 3.8.1 it hangs after this line:
---
windfarm: Drive bay control loop started.

And then i'm getting RCU stall call traces.

On Linux 3.2 it hangs too but not at the same place.
It hangs after some SCSI message.

Have anyone tested Linux 3 kernels on PowerMac G5 recently ?

Regards
