^^^^^^^
here it is!
I'm working on w83877 detection/configuration. Yet, try to force EPP mode
with flag 0x3... this may avoid some timing problems.

I suspect data corruption... Please, try without any disk inside the drive
during boot. Try fdisk once the system is started (without any disk either),
you should get "medium not present" error. Then try with a disk inserted.
I've noticed in one of your other mails that vpo driver hangs when it requests
the ppbus (I remember [ppbreq])... I'm working on some ioctls that would
allow us to query the state of the bus and debug it more efficiently.
