ohci_hcd dies sporadically

Description of problem:
Now and then the external mouse of my laptop stops working and syslog says:
Jun 8 12:45:12 vaahtera kernel: ohci_hcd 0000:00:02.0: HC died; cleaning up
Jun 8 12:45:12 vaahtera kernel: usb 1-1: USB disconnect, address 2
Jun 8 12:45:12 vaahtera kernel: ohci_hcd 0000:00:02.0: leak ed dfd3b040 (#81)
state 0 (has tds)
After this happens, disconnecting and reconnecting the mouse doesn't help.
Version-Release number of selected component (if applicable):
Haven't found any clear sequence that triggers this, this usually happens a
while before the kernel hangs completely (nothing works, keyboard doesn't
wokr, doesn't respond to pings).
I'm also a victim of bug #240982
This also happens with kernel-2.6.21-1.3228.fc7
Still in kernel-2.6.22-1.33.fc7
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.
I am CC'ing myself to this bug and will try and assist you in resolving it if I can.
There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?
I have added the USB subsystem maintainer to this bug as he may wish to add any
Does your laptop support USB 2.0 or is it an older model?
Are you running this under vmware?
If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
Well, since then I've switched using FreeBSD on the laptop, because the ata
driver crashes the kernel on the machine now and then (a known bug, but I got
tired waiting for the fix).
Anyway, the USB subsystem dies also with FreeBSD, so this seems to be a
hardware issue and can be closed as invalid as far as I'm concerned.
