Hi,
I have also problem with FC4 on an iMac G5.
I could install FC4, after reboot I could/can login. But within some
minutes of using, the system doesn't respond and I get the following
messages on the console:
ata1: command 0x35 timeout, stat 0x50 host_stat 0x4
hda: lost interrupt
mpic_enable_irq timeout
ata1: command 0x35 timeout, stat 0x50 host_stat 0x4
...
With FC4test3 it didn't happen this.
