IFSs are not device drivers in this sense. They don't have a device
driver header, so they can not appear in the device driver chain. If
exeinfo does not work, it takes a module table scan to convert the cs:eip
to a module name. This is cumbersome and newer kernels do this for you.

This is the point when the device drivers are activated, so hardware
problems tends to show up here as traps.

I recommend you try:

<http://www.memtest86.com>

This will rule out failing RAM to some extent.

You probably also should let dfsee check out the partition. Of course if
you can zip, format and restore the partition, that would be useful too.

IIRC, the trap addresses are pretty consistent, so you could have a data
problem on the drive.

While working on this, get:

<http://home.earthlink.net/~steve53/os2diags/DumpTrapScreen.zip>

and a blank diskette and save yourself some writing.
