[Cbe-oss-dev] Problem with rebuilding latest Linux Kernel for PS3

You looked at it before, but I can still say that my manual still
works with Fedora 8. even on FW 2.41. I tested it again.
(http://www.bohmer.net/ps3_stuff/install-fedora-8-on-PS3.html)
Many people have used this manual, without major problems.

If it is not working, then there must be something else (done) wrong.

> 4 -Perform step C

See above.


Kind Regards,

Remy
