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.
