Bad, the two register dumps you and Mike mailed don't make very much
sense; the epc register is pointer to completly different routines.
What both reports have in common is that the kernel dies after the
initialisation of the loop device. The loop driver is actually
``harmless'' as it has no SGI specific code. The next driver to
be initialized would be the SCSI driver, so the problem is there.
This and the useless epc values might indicate a problem with the
hpc dma.
I wonder if the DMA engine in the HPC might still be active?
I'm going to try to solve the problem by starring at the source. If
this doesn't help, could you guys please run a special debug kernel
that I'll make for you?
Ralf
