Comment 79 for bug 550559

OS: Ubuntu 10.04.2 LTS up to date

Never ending story... :-(

A few months the problem appeared once in a blue moon. In the last two days i extended my raid and lvm, and growed the ext4. All was running fine, although the HDs were under heavy stress. I rebooted this morning, and installed a new kernel (1) as suggested. And now i get this again from time to time:

ata3.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x0
ata3.00: irq_stat 0x40000008
ata3.00: failed command: READ FPDMA QUEUED
ata3.00: cmd 60/00:00:3f:36:12/01:00:6c:00:00/40 tag 0 ncq 131072 in
                res 41/40:58:e7:36:12/00:00:6c:00:00/40 Emask 0x409 (media error) <F>
ata3.00: status: { DRDY ERR }
ata3.00: error: { UNC }
ata3.00: configured for UDMA/133
ata3: EH complete

Boring! :-( Tomorrow i will try the old kernel. Report will follow the next few days.
