Hello again,

I wrote (yeah, why do I always find more info after posting?) minutes ago:

attempting this, dmesg displays:
[  687.741109] parport 0x378 (WARNING): CTR: wrote 0x0c, read 0xff
[  687.741119] parport 0x378 (WARNING): DATA: wrote 0xaa, read 0xff
[  687.741122] parport 0x378: You gave this address, but there is probably no parallel port there!
[  687.741144] parport0: PC-style at 0x378 [PCSPP,TRISTATE]
[  687.838463] lp0: using parport0 (polling).


cat /sys/devices/pnp0/00:0a/resources
shows the resource as disabled. Even after
echo "auto" > ..resources
this remains so.

Yeah - we finally were able to update the BIOS, unfortunately, it does not fix the bug.

Ok that's it for now,
again, I'd be happy for any pointers,
Yours
