Kernel crash on 2.4.16



All,

I've posted here earlier regarding a kernel crash we were seeing on kernel 2.4.13,
on our embedded hardware...  We have recently upgraded to 2.4.16, and are still seeing
crash issues. 

We are running Vanilla 2.4.16 (including some of our own device driver modules) on a
PowerPC 7410, with the root partition being EXT3.  

We have a test which creates a EXT3 partition, coppeis /usr/bin to it, reboots,
deletes the files, reboots, and starts over..

When running this, it seems to run for a while and then we start getting these
crashes:
