[parisc-linux] ASP Parallel port driver broken on HP9000/730

[M. Grabert]

Hello there,

As I said before (in another mail), the ASP parallel port driver
is broken: the kernel hangs (lastest CVS, one hour ago).
Everything's fine just without ASP parallel port driver!

Unfortunately I don't know how to redirect the kernel output
to the serial console, so I can give you only some hints...



parport_init_chip: initializing bidirectional mode.

The kernel makes a memory dump from 0000 to 097f,
then:

High Priority Machine Check (HPMC): Code=1 regs=c034a080 (Addr=00000000)

Then follows a dump of the processor registers:

PSW: 00000000000001000000000000001111
r0-3   00000000 c02eb800 c0246328 c1f30788
r4-7   0000002c c1fe5220 f0824800 ffffffdf

sr0-3  00000000 00000000 00000000 00000000
sr4-7  00000000 00000000 00000000 00000000

IASQ: 00000000 00000000 IAOQ: c026e458 c026e458
 IIR: e840c000     ISR: 00000000   IOR: c0246328
ORIG_R28: 00000000


NB: i typed all this stuff, no copy'n'paste; so perhaps
there are some errors ... 

BTW, no HIL connected, just serial console (but since
the kernel hangs before, i cannot see any output :))).
No PC parport selected, no support for foreign h/w,
no IEEE 1284 transfer modes ...)


hope that helps!
