[parisc-linux] 715/50 hang - more info
Wed, 17 May 2000 20:26:35 -0500
When I was trying out a C180, I ran into problems in about the same point
in boot. In my case it turned out to be a problem in the lasi_82596
driver. It was executing the interrupt handler before the driver was finished
being initialized. You might try editing lasi_82596.c to make i596_debug
#define I82596_DEBUG 10
int i596_debug = I82596_DEBUG;
int i596_debug = 1;
This will get you lots more debug messages from the driver so you can see
if it's doing something funny. I have a hacked version of lasi_82596.c
that may have worked around this problem and some others that I was finding,
but I'm not really sure what state it's in (it may not even compile) as I
haven't had time to play with it in over a month. I'll email it to you so
you can see if it takes you any further.
