FC3 kernel problem Re: FC3 and ruby woes

[James v. Z. <ja...@dv...>]

Confirmed FC3 kernel issue.

Compiling 32bit Athlon fc3 kernel with ruby patch results in an unstable
kernel that crashes inconsistently on launch of X.

This is duplicated using another standalone box without configuring
multiple consoles, just installing ruby kernel only.

What can I do to provide some debugging info?

I shall test further to confirm ruby patch against fc3 kernel as source
of issue. 

Anyone aware of FC3 quirks that might impact ruby?
such as gcc3.4.2-6.fc3? 

recalling the inlining issue : One can't just patch vanilla 2.6.9 with
ruby and expect it to compile under FC3, it will fail with inlining
errors, as do a small handful of other modules. However, patch the FC3
kernel and it compiles, but does it compile correctly?

Perhaps I should just wait for 2.6.10-ruby.
