Just had an oops w/ 2.6.24.2 and was about to send the attached to
lkml. Although it happens less frequently in 2.6.24.2 and I don't see
btdelconn in the single Oops I've had in 2.6.24.2

Just one bluetooth mouse.

I'll attach the plain text file will most of the output requested by

/usr/src/linux/REPORTING-BUGS

the outpu of DMESG from after booting to recover from the Oops is at the bottom.
