I am also experiencing this bug on Ubuntu Hardy running on SATA disks.
Below is an output of the errors (seem to be intermittent - didn't have
them for some time and it's occurred twice today, resolved usually by
rebooting - apps freeze and am unable to shut down normally):

Below is output of uname -r and lspci:
gma...@lianli:~$ uname -r
2.6.24-19-generic
This also occurs on other machines with similar hardware in the office
so I am fairly sure that it's not related to HDD faults etc.
Thanks.
