if the lockups are still there even with the new driver, then could you
give the NMI-watchdog a try? Try the 2.1.90-B version,i've posted it to
linux-kernel recently. (i'm not attaching it, it's big). To debug the
lockup you should do this:
- apply the patch
- configure NMI watchdog to yes in Char Dev/Watchdogs
- reboot into the new kernel
- wait for a lockup, a 'double oops' will be generated, one oops
per CPU. Write the 'Call Trace' lines down and send them through
ksymoops. (register content doesnt matter)
[the NMI watchdog checks other spinlock-related semantics too, so it might
be that you get an oops much earlier.]
