Do you have any indication  how  far  it  comes?  Do  you  have  kgdb
working, or a good BDM debugger (i. e. one with MMU support)?

It depends on what you mean with 2.3; it's just two days that I  have
2.4.0-test5  running  stable  on  TQM8xxL boards. This is the _first_
kernel after 2.3.18 that ever ran for me on a MPC8xx. And  even  this
is  only  when  you  fix cache problems in string.S (either by simply
replacing the file with the version from 2.2.13, or by applying Dan's

Sorry, I don't have any RPX boards here to test, but  I  have  tested
three  systems  (2  x 850 and a 860), two of them under > 24 h stress
tests (with things like compiling the linux kernel  on  the  target),
and I had not a single problem since.

In  case  you're  interested  -  I've  put  my  patches  against  the
2.4.0-test5  BitKeeper  sources on our FTP server (the "COMMON" patch
includes all I neded to change for TQM8xxL  support  to  the  current
kernel;  the "TQM" patch is probably of little interest since this is
just needed when you use the old TQ monitor instead of PPCBOOT):

Real programmers don't comment their code. It was hard to  write,  it
should be hard to understand.
