freebsd 5.2 (was 5.1) ohci driver causing a panic (more details)

Thu Jan 15 22:32:22 PST 2004

I upgraded to FreeBSD 5.2 to see if the changes to the ohci driver would
fix the problem.  I didn't think they would, but it was worth a shot.
It didn't fix it, but I now got kernel dump from the panic.

panic: ohci_add_done: addr 0x0ef5af00 not found
panic messages:

cpuid = 0;

All I need to do to trigger this panic is unplug my USB UPS and plug it
in and let the ups.pl script read from /dev/uhid0.

Let me know what other information would be useful.

Thanks,

Michael
