We have some problems with DMA on BenH's kernel from yesterday (30.10.2001),
(maybe we've got it later).

Same problem with as described in
http://lists.linuxppc.org/linuxppc-dev/200110/msg00371.html

Anybody know what is causing this problem or how to get an older,
but more stable BenH tree without it?

There's some diffs from the last couple of weeks against official kernels
here:  http://debian.jones.dk/auryn/kernels/patches

I rewrote the IDE timing code a few days ago, and well... it wasn't
completely bug free ;) Well, it should be ok now, the timings put
into the controller are the same as Darwin and MacOS 9 use for
a given disk, except for some older machines (OHare based) where
I suspect some HW problems and so limited the MDMA cycle time to
150ns (which is approx MDMA1).

Except from that, my kernel got no major change lately, only small
fixes here or there.

Note that you should probably post diffs against _2_4_devel, they
would be a lot smaller :) My tree is a "child" of _devel and
my changes are regulary pushed upstream.

Ben.

Open Firmware debugging through Ethernet

Hi,

I stumbled across this today, that might be useful to kernel hackers:

Open Firmware debugging through Ethernet fram another machine.

Kind regards,

Rather, look at this one:

http://developer.apple.com/technotes/tn/tn2004.html

It's this technote that explains how to start the telnet server on the
target machine.

Cheers
