When I write to the drive (hdg, seen as scsi ID 0) with cdrecord, it will
write successfully for some time (usually 30 MB or more, sometimes even
completing a write), whereas in older kernels it would fail between 1-4
MB.
In earlier 2.4.20-pre kernels, the PDC20268 drivers would report timeouts
resetting the card upon rebooting, and the only way to regain control of
the CD-R was to power the machine down.  This seems to have been fixed
along the way.
Below is pertinant information.  The system completely hangs, but there is 
no kernel oops.
