Red Hat Bugzilla – Bug 437083
p54usb locking spew and dropped connection
Last modified: 2008-06-06 15:13:47 EDT
Description of problem:
I have a ralink 2500 pci card in this rawhide box, it doesn't scan i.e. bug
430038 I suspect. So there's an additional usb wg111 v2 dongle plugged in,
there's a large pile of locking errors logged that seem to refer to both drivers.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot with both devices connected.
lots of spew about locking problems.
The usb device does work for a bit, but after a relatively small amount of data
is transferred then a No ProbeResp is logged and that's the end of the device
until removed and reinserted.

better dmesg log
Seeing as a mix of devices is confusing this a bit, I pulled the pci card out,
and here's the dmesg of just the usb p54 device up to the point where enough
data has been transferred to drop connection
With the same kernel as mentioned in #437085 connection still drops after enough
data is transferred (during sustained cpu load if that's a possibly trigger),
ripping out the device and sticking it back in lets it reassociate and go again
until the next drop. Though the unplug gives similar spew to #2

dmesg with an unplug spew if that helps
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
I seem to recall a bug like this being fixed some time back. Can you recreate
the issue with current f9 kernels?
Looks good in F-9 x86_64. No locking spew and large downloads complete
successfully during ludicrous CPU load
