Please send this to sparclinux@vger.kernel.org.
One thing I can tell you is that 2.4 is not as stable as 2.2 on sparc32
systems, especially 2.4.18. If you want to try 2.4 on sparc32, I
strongly suggest 2.4.21, or even 2.4.22-pre's. Likely, you'll be asked
to try atleast reproducing it on 2.4.21 before you get any help with
this bug. 2.4.18 is very old.
If you want stability (and don't mind going back to ipchains and ext2),
stick with 2.2.x on critical sparc32 systems.
