2.5.5-dj2

got this either unplugging and plugging my usb printer from the hub, or turning it on and off (don't remember the exact timing).

Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.

Were you sending data to the printer at the time?

And does this also happen on 2.5.6-pre2?

thanks,

greg k-h

There was a print job spooled in CUPS at the time, so I assume it was trying to talk to it in some way. I'll have to let you know about 2.5.6-pre2 (or some later version) in about a week, as that machine is in my dorm turned off for spring break this week.
