Comment 24 for bug 120839

I'm getting similar error messages but without the 30 second lockups. This is on an old Dell GX110 desktop (PIII/700, Intel chipset, using ata_piix module, with Samsung SP2514N PATA disks). Running Feisty, fully updated, with kernel 2.6.20-16-generic, using libata for the two PATA disks. Controller is UDMA/66 while disks are UDMA/100 so ATA uses 66 from bootup.

ACPI is enabled if that matters, and kernel messages indicate it's working.

The errors started on 23 Dec when I updated the kernel (aptitude log):

[UPGRADE] linux-headers-2.6.20-16 2.6.20-16.32 -> 2.6.20-16.33
[UPGRADE] linux-headers-2.6.20-16-generic 2.6.20-16.32 -> 2.6.20-16.33
[UPGRADE] linux-image-2.6.20-16-generic 2.6.20-16.32 -> 2.6.20-16.33

The errors from /var/log/messages are intermittent but always the same, e.g.:

Can anyone comment as to whether these errors are significant?
