I've put a snapshot of current CVS kernel sources into
oss.sgi.com:/pub/linux/mips/src/kernel/linux-19991206.tar.gz.

Most important for you guys out there the upgrade to 2.3.21 and a number
of bug fixes.  Try it, break it.  Again ;-)  Aside of this this kernel
also has a good part of the 64-bit stuff.  Not all of it, I'm maintaining
the 32-bit kernel, the Indy 64-bit and the Origin kernel as separate
trees to prevent bugs from creeping from on tree in the other.

Hi Ralf,

This compiles very well (i386 cross-compiled) unless I add serial console
support, in which case it finishes like this:

mips-linux-ld -static -G 0 -T arch/mips/ld.script.big -Ttext 0x88002000

The CVS 2.2 source still compiles.

The CVS now has a couple of fixes, could you retry?

" 6.2 Self compiled kernels crash when booting.

When I build my own kernel, it crashes. On an Indy the crash message looks like
the following; the same problem hits other machines as well but may look
completely different. 

 [...]

This problem is caused by a still unfixed bug in Binutils newer than version
2.7. As a workaround, change the following line in arch/mips/Makefile from: 

   LINKFLAGS       = -static -N
 
to: 

   LINKFLAGS       = -static"

BTW, little endian semaphores for R4xxx and TLB miss handlers for R3xxx are
broken in this snapshot. This is fixed since yesterday and 2.3.21 is happily
running on a /260 and a /133. If you want to play around with recent kernels I
suggest a fresh cvs checkout. Instructions can be found at the above URL.

Hope this helps.

Harald

Serial console is not working in 2.3 yet.  I know how to fix it for when
it is included on the command line, but what I came up with for detecting
it from the PROM enviroment is a bit strange.

Currently you cannot revert to a previous snapshot. Due to information from
Ryusuke Konishi the current data structures don't support this.

So for now you will have to rely on rsync or a similar tool.
