Subject: Re: [BUG} usb-serial regression in 2.6.21-rc2-git3

Still no improvement on the b0rken usb-serial resume support in -rc*.

Today I got this ooops on resume from RAM.
Slightly tainted kernel this time (vmware), but not previously
on similar crashes.  I cannot yet get it to "crash on demaind",
so you'll just have to live with it this time.

All USB was dead until after a reboot this time.
