I have 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 ... Any idea what's this? Is it only for me, or it is reproducible on other machines? What should I try? Should I create a bugzilla entry? Zoltan
