Hmm... I didn't realize it was getting wrapped. I'll try to avoid that
next time. (If my next attempt to avoid the word-wrapping fails, then
I may not have enough free time to move to a sane mailer again for 2-3

The interesting thing is that we've done sleepy things like down() just
prior to this. Do you have CONFIG_PREEMPT and CONFIG_DEBUG_SPINLOCK_SLEEP
enabled? If not, please turn them on, see what happens.

PREEMPT is enabled. DEBUG_SPINLOCK_SLEEP isn't. I'll enable it now.
