Hi,
without knowing what i am doing i got as far as inquireing the SCSI bus.
Now it hangs in scsi.c in down(&sem) ...

----------------------------------------------------
scsi_do_cmd (host = 0, channel = 0 target = 0, buffer =80207d00, bufflen = 
256,)command : 00  00  00  00  00  00  00  00  00  00
Adding timer for command 802f8e00 at 384 (800e3e60)
internal_cmnd (host = 0, channel = 0, target = 0, command = 802f8e45, buffer =
bufflen = 256, done = 800dc3c8)
queuecommand : routine at 800eac44
esp_queue: target=0 lun=0 N<00,00>!use_sg

pmaz-aa.c: PMAZ-AA dma_irq_p called esp_irq: 4
esp: Selecting device for first time. target=0 lun=0
<SLCTNORM>leaving internal_cmnd()
Leaving scsi_do_cmd()
scsi.c: spin_unlock_irq
scsi.c: down(&sem)
-------------------------------------------------------

What is this down ? I am not that used to semaphores etc ... might
someone shed a light on me :) ...

BTW: I solved the IRQ thing ... was like Harald said ... i am
using TC0+slot at the moment but i am sure this is wrong but
works on my 50000/1xx is a *FIXME* thing :)

Flo
