I've installed Lubuntu 12.04 on a Powerbook G4 (PowerPC 1GHz, 1 gb ram, Geforce MX 440). Everything works perfectly except the startup and shutdown. To startup my system I have to wait about 3 minutes (and similar time to shutdown)

Giving a look @ /var/log/dmesg I noticed the following

[drm] nouveau 0000:00:10.0: Detected an NV10 generation card  (0x017900a5)
checking generic (b8004000 151800) vs hw (b8000000 80000000)
fb: conflicting fb hw usage nouveaufb vs 0Ffb NVDA,Displ - removing generic driver

The only issue concerns Nouveau ... inside my /var/log/kern.log says what follows

BUG: soft lockup - CPU#0 stuck for 22s!

I've booted passing the "nouveau.modeset=0" parameter and the system boot in 15 seconds but with 4 bit graphics -- Any idea how to fix?

Thanks in advance for any help
