Hi guys.
I was wondering if any progress has been made on the Wallstreet /
ethernet problems issue that was being discussed a while back?
I'm seeing the same issues - real slow connections, a shedload
of packet collisions and occasional crashes when the disk is
grinding.
I can probably gather some more stats if that would be helpful.
Wallstreet II, kernel 2.2.14p9 (I know, I know, but it seems pretty
stable and apart from the ethernet issue it all works),
standard LinuxPPC 1999 install. 192MB memory, some kind of
IBM disk.
If there's a patch out there, or a newer kernel fixes it, I'd be
grateful. I'm a bit wary of the 2.3 kernels - I need working
hfs as well as linux, unfortunately - but I'm willing to give
them a go. ISTR there was some question of whether it was the
disk itself that was causing the problems - If that's the case
I'll just go and shell out for an 18gig drive (not that I've been
looking for an excuse, or anything ;-)
I'd have a go at hacking the code if I had the time, but I'm working
18+ hour days at the moment. Such is life <sigh>.

Is the Wallstreet II (never heard that name) the same thing as a
lombard? Does it have a bronze keyboard? I've got a lombard running
2.2.15pre20 from the linuxcare linux-pmac-stable kernel source. I haven't
had any crashes other than when I was writing a kernel module... but that
was to be expected (Note for newbie kernel module writes: make sure to
sync a few times before reading a your new (untested) /proc entry ;-) As
far as ethernet goes, I haven't seen any problems. I can get over 7 Megs
per second without problem. You might check to see if your connection is
half,full, or autonegotiation on duplex. I had problems with auto and
full on another linuxppc machine (G4 sawtooth 450). I seem to get the best
performance with setting the port on the switch to half duplex. I'm not
sure if this is a problem with autonegotiate or what...
Hope this helps,
Sean

I haven't seen anybody working on this. After the initial discussion
(especially with Benjamin Herrenschmidt) it seems clear that this is
a know problem which can cause Tx packets to become corrupted.

... and probably corrupted data on outgoing connections.

Thanks, but this is probably not necessary - the problem seems clear.

Same for me - I don't know enough about the BMAC hardware, and don't
have time to learn it right now.
I sent a message asking for help to Benjamin Herrenschmidt and Paul
Mackerras (on Monday, April 17), but got no reply yet :-(
