Note that this bug was present in earlier 2.6 kernels, too...

How reproducible:

Run cerberus ;)
Comment 1 Pete Zaitcev 2004-08-26 17:27:54 EDT
Rik, how is USB involved in Cerberus in this case?
E.g. did you attach any disks or is this just a keyboard?
Comment 2 Rik van Riel 2004-08-26 20:25:52 EDT
I was running the disk IO stress test to a drive on usb storage, in an
enclosure similar to the one I sent you.
Comment 3 Dave Jones 2004-11-27 17:33:32 EST
mass update for old bugs:

Is this still a problem in the 2.6.9 based kernel update ?
Comment 4 Dave Jones 2005-04-16 01:34:52 EDT
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
