Subject: Re: usb_mon oops Re: tcpdump crashes 2.6.29.1 (and 2.6.29-rc5)

Ok, I've confirmed that it's usbmon under 2.6.29.1 on x86_64 which causes
complete system lockups when doing 'tcpdump host ##.##.##.##'.  I
compiled usbmon as a module, started a tcpdump and couldn't get a
crash. 

Loaded the module with tcpdump still going, no problems.  Stop and
restart tcpdump, bang!  Instant hang.  I'm now building 2.6.28 to see
if that works properly or not.  I suspect I might have to go back
farther, but I'm not sure.

Any suggestions of a known good state I should start bisection from?

Thanks,
John
