Hi Joseph,
this still occurs for me with the 3.5.7 from that link (and with current
raring), but as stated not with the 3.5.0-19 from quantal.
My test procedure on my box is:
* Fresh boot
* Log in via kdm as my default user
* Wait for my standard KDE desktop to settle
* K menu->Leave->Switch user
* select new session
* Login as my other user
As my other user:
* K menu->Leave->Switchuser
* select the existing session for my main user
And that blew up this time for both 3.7.0-7-generic #15-Ubuntu and
3.5.7-030507-generic #201210130556
and I've checked again, 3.5.0-7 is still good for me - bounced back and
forward 5 or 6 times.
I also had a blow up on 3.7.0 when running an SDL game, also triggered
the -35
dmesg on the blowups from the user switching test:
3.7.0-7-generic #15-Ubuntu booted, logged in, did switch user, did switch back
- bang
