Subject: Re: Kernel 2.2.10 and sonic ethernet chip
I cannot find ANY udelay in the sonic.c, sonic.h or macsonic.h.
I've tries to include some udelays here and there, but without much criterion.
Anyway, nothing changed.
I've put sonic_debug to 3 and putted the relevant /var/log/messages in the
attachment.
Best regards,
Peter
(See attached file: messages)
Debug the SONIC init code. Hint: add or prolong the udelays between
register accesses, find the critical register access, then figure out how
to detect a 'SONIC busy' situation that's apparently biting you.
Double check that the memory you allocated for the SONIC data structures
is properly marked as non-cacheable (nasty mm macros, but a quick and easy
check is to make _all_ RAM non-cacheable in the mm_init() function called
early in kernel setup).

If I hear that one more time I'll stop replying to that sort of posts
altogether. Obviously, the SONIC driver worked for me, reliably that is,
under Linux 2.0.36 and 2.2.whatsitsface from May 1999. There were cache
mode issues in 2.0.36, and people mostly on Q700 reported trouble with
SONIC in 2.2 but no one ever sat down to investigate it IIRC.
The error message indicates a subtle timing problem in the driver init
code. The SONIC core code is shared with MIPS, maybe someone from the MIPS
port emoved the udelays - David should know about that, and he should know
if any endianness issues might be responsible for this problem. I'm not
looking at the code BTW so it might all be nonsense.

Good luck. If you're experienced enough you could sure fix the driver in a
day or so.
