I had the same bug in breezy on my 2*2.0ghz G5 (powermac7,3)and I compiled the 2.6.14 kernel. It ran fine. This bug was said to be solved in dapper and I upgraded my system. Same bug.
My own kernel did not run anymore. I've compiled 2.6.16 (and got random hangs) and finally 2.6.17. Now I've got a stable system and fans run at the good speed. -- G5 needs i2c-keywest for proper operation of therm_pm72 https://launchpad.net/bugs/27269 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
