Hi to all members of the linux gigabit family,
thanks Bernhard for the hint. After installing Eric's stuff,
the kernel panics are gone, which let to a big improvement of
operational state (50 gig fscking is s/fs/fu/g painful).
But some stranglets remain. One effect was, when rloging to
the server and simply hitting <left arrow>, I was able to
freeze the xterm session?!? Telnet behaviour was different,
and not so easy to stall. Obviously, this does NOT happen,
when using 100BT of any fashion. I presume any border cases
in very small packets, but couldn't investigate any further,
because it was 4.30 in the morning and daily backup was
waiting... But now, I can quickly switch between a 3c305 and
the gnic :-)
Any more ideas?
Hans-Peter
