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.
