Okay. This looks like a generic problem with the SCSI extended partition code.
I have seen several senarios which result in the problems described above.
1. Adding the CD-ROM filesystem extentions did it for me.
2. Compiling the kernel under GCC v2.2.2d did it for some
3. Now, looks like pl4 has blown it in this case.
I was trying to work with Eric (the author of the CD-ROM stuff) to find
out what goes wrong, but my disk controller flaked out and I haven't
had a machine for the last week...
Maybe Drew would like to look into this as a generic SCSI problem? I don;t
know how far off the much-awaited version 2 of the SCSI drivers are, but
maybe this is a quick-fix.
I'm going to get back on this as soon as my controller is repaired (hopefully
this weekend...)
