I managed to find some widgets and hook the serial output of the HP to my
PC, so I'm sending along the entire boot output, as well as my .config.

Re: [parisc-linux] 715/50 hang - more info

[Bob Pflederer]

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
10:

#define I82596_DEBUG 10

#ifdef I82596_DEBUG
int i596_debug = I82596_DEBUG;
#else
int i596_debug = 1;
#endif

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.

I reached the same conclusion you do.   Actually, I got your reply just as
I was about to delve into all the nice output of I82596_DEBUG 10 :)

Unfortunately, your modified driver doesn't seem to help... still crashes
at the same point :(

I'm going to investigate this further.  I'll let you know what turns up.

Re: [parisc-linux] 715/50 hang - more info

[Ulrich Strelow]

Hi Chris,

I had the same problem on my 715/33 with lasi_82596.c.
I emailed Helge Deller who made the last changes to
this driver and he told me that there seems to be the
problem that not all interrupts from the i82596 are
delivered to the interrupt routine. The result of this
is that all 16 xmit buffers will get filled and then
the kernel hangs.

He also told me that he will have no time until 23rd
of May (approx.) to find the reason for this and to
correct it. So right now there is no way to use
NFSROOT on a 715/old.

Bob Pflederer's observations concerning I82596_DEBUG
are correct. But it is sufficient to #define it to 3
to make the driver work.

That's what I came up with as well.

Well, I'm going to keep playing with it over the next few days, although
I'm not sure if I'll have any success...

If I succeed in fixing anything, I'll be sure to let everyone know.


Thanks,

Hi,
  I have just committed changes to drivers/net/lasi_82596.c and
drivers/gsc/lan.c.  Fairly big changes to lasi_82596.c, partly
just tidyup, partly improvements to cache handling.  It is still
not perfect but is a _lot_ better than it was.  The change to
lan.c was to use a different probe function on older h/w (like
my 715/75), where we need to swap the MPU_PORT, as per the message
from prumpf.  If the driver seems completely dead for you, try
enabling/disabling that word swap, and please let me know that
you needed to.

All success or failure reports welcome :-)

Richard

Success!  The driver works fine.  I made no modifications for word swap
(on a 715/50).

No let's see what else I can break :)

Re: [parisc-linux] 715/50 hang - more info

Hi Richard,

great work: for the first time I was now able to boot
using a NFSROOT filesystem on my 715/33. Everything
works well until the sash shell prompt.

So device support for my 715/old is nearly complete:
serial console works well and SCSI has been tested
using a HP DAT drive. Putting a real ext2 fs on a SCSI
disk is a bit complicated for me because I do not have
direct access to a Linux PC with a SCSI board. But I
will test this real soon and report back.
