[Bug 539467] Re: Frequent ATA errors and disk corruption

[lightweight]

I'm getting the same sorts of problems every time I attempt a suspend on
my ASUS Z62E laptop with

Linux 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010
x86_64 GNU/Linux

The machine doesn't suspend, and eventually returns to the X login
window for unlocking the screen (not the GDM login) with a very high
load average, and a lot of CPU wait (unsurprisingly). Ultimately, the
only fix is a reboot.

Note, this laptop was recently upgraded from Karmic, where suspend
worked without problems. It also worked after the initial upgrade to
Lucid, but possibly since a kernel update, this problem has sprung up
probably starting around 8 May.

The error messages start on suspend, either via closing the lid or
explicitly selecting suspend from the Session menu. In syslog, the only
temporally related event is the DHCPREQUEST, which I've included below.
