Hi Is there somebody on the list that could assist me in interpreting the log messages I've started to get, attahced at the end of the post. I have a machine with FC6 and the latest kernel and it has started to act up, the system will hang for a minute or so, at the same time the suspicious log messages appear. It is the hard disk I have the root partition on. I haven't noticed any data corruption and I've backuped my home directory. Is the the only thing to do to buy a new disk and reinstall? Thanks Markus May 6 09:52:35 zeus kernel: ata3: EH in ADMA mode, notifier 0x0 notifier_error 0x0 gen_ctl 0x1501000 status 0x400 May 6 09:52:35 zeus kernel: ata3: CPB 0: ctl_flags 0x1f, resp_flags 0x2
