Sorry for the delay, your mails didn't make it into my inbox, and I
usually just mark threads on which I'm Cc'ed as read in my lkml mailbox,
thus I didn't notice it earlier. Any traces of the lost mails on your
side?
The patch works as expected, no Oops in sight. Regarding the
reproducability, it might be that it was easier to trigger on rc1. When
I retried today with rc4, I only got 2 Oopses in a minute, while the
first test had spitten out about 20 Oopses in 10 seconds (not sure if I
really had rc1 running back then, though).
