[cobalt-users] RaQ550 kernel update causes oops?

[Chris Adams <cmadams@xxxxxxxxxx>]

I (finally) applied all the current updates to our RaQ550s yesterday,
and last night one of the crashed (no remote access).  We were able to
restart it from the front panel, and after it came up, I checked the
logs and found a kernel oops:

After that, there were another 5473 oops messages, but in my experience,
only the first oops is meaningful (after that the kernel is off in the
weeds anyway).

Has anyone else seen something like this?  Is there a way to send this
to "official" Cobalt/Sun support?  I actually considered paying the $95
for the online support form, but they don't even have RaQ550 on the
product list (and I consider it rather absurd that I should have to pay
for their problem).
