I have some problems with kernel 1.3.37. Although it seems to be the
most stable kernel of the 1.3 series, I still have some strange
phenomenas... The following kernel oops occured on 486DX2/66 VLB-board
with an Adaptec 152x compatible SCSI controller, a Conner floppy
streamer mounted and zftape-v0.1 module loaded... And xdm running,
X library version 3.1.1, 256 colour server. (Yes, I should upgrade
to 3.1.2 lib's, but you haven't seen the last phone bill...)
Anyway, the first one is not related to zftape (module unloaded):

The next one was within a module (zftape?):

Finally, today, after 3h of working (doing a backup on the tape),
funny coloured characters on switching the console and 30 seconds later:

Any ideas what's going on?
