Panasonic LF-D211V DVD-RAM hangs IDE

[Laurent Itti]

Hi all:

I have seen several similar reports already, but could not find 
a solution in the replies I have read so far.  So here we go:
I have a Panasonic LF-D211V 4.7GB DVD-RAM drive (UDMA/33) with a
brand new 80-cond ATA/100 short ribbon cable. Kernel is 2.4.6.

- If I hook it up to a CMD649 IDE controller, the drive is set to
PIO mode and the machine hangs while I attempt a mke2fs on the disk
(no message; just hangs)

- if I hook it up to a motherboard with VIA vt82c686a, the drive
is set to UDMA/33 mode and appears to work for a while, until
some error comes in (while I attempt to transfer a big file),
and comes again until DMA gets disabled, at which point the machine
gets into an infinite loop of trying to reset the drive (see below).

In passing, if I do a mke2fs -b 2048 /dev/hdb on a disk, it works,
but I cannot mount the disk.  Pre-formatted UDF disks mount ok,
though. 

any suggestion would be most appreciated!
