Bug in SCSI driver with SMP with NPTL?

I have the following system:

Tested with Source Mage GNU/Linux on a vanilla 2.6.3 kernel and Fedora Core I
with the 2.4.22-1.2174.nptlsmp kernel (and prior ones as well), both have
glibc+NPTL support (glibc 2.3.3 [20040310 snapshot] on SMGL, 2.3.2-101.4 on
FC1).

And periodically I get the messages below and the system is "frozen" during
whatever is going on. I've also attached my config from this. If I disable SMP
(in either SMGL or FC1) I cannot repeat the problem.
