Public bug reported:
Running 9.04... all updates applied.
The problem manifests during sustained downloads from the internet, e.g.
downloading an Ubuntu CD image, or running a large update with update-
manager. The result is that the disk goes read-only without warning,
and the trace included below in the dmesg.
First noticed the problem in the kernel current on 30th March (not sure
what number that was). It was fixed by a subsequent update, but
recurred in 2.6.28-11-generic #41-Ubuntu SMP Wed Apr 8 04:38:53 UTC 2009
i686 GNU/Linux
...but now seems to be fixed in 2.6.28-12-generic #43-Ubuntu
The workaround suggested was adding irqpoll and all_generic_ide which
solved the problem but seemed to cause other serious instability in the
system (random freezes with blinking caps lock).
