[pxc] smp 2.4.x oops

[Alessandro Rubini]

Hello Chanop.

I'll investigate, thanks for the report. Unless I'm able to reproduce
it on UP with SMP kernel, though, I'd need the output of ksymoops on
this data. I'll tell you if I need it.

Hmm.... irq sharing works for me, actually.

Note that the problem may be xfs-related. On the RTAI list one
reproducible bug just turned out to be an fs issue (found by running
the same tests on NFS files instead of local ones).

Well, if you have a kernel map (offlist), that would be great. I'd
also need to know the amount of RAM and /proc/module before the oops
(to estimate the address where pxc.o is loaded. "nm pxc.o" would be
useful as well.
