I have been trying out the new 2.4.0 kernel and am unable to get
raid5 to work. When I install the raid5 module with
modprobe raid5
I get a segmentation fault and the following error appears in the dmesg output:
raid5: measuring checksumming speed

when I modprobe raid5 again no errors are reported and dmesg has the following
md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27
md.c: sizeof(mdp_super_t) = 4096
raid5 personality registered
Of course raid5 cannot be compiled into the kernel since it also gives the
same error as above and dies.
Any ideas?

It works if you compile the kernel with the processor type set to Pentium
II or higher, or disable RAID5. I've been meaning to report this one, but
2.4.0 was released before I had time to test the last prerelease, and I
haven't had time to test the final release yet.

Sure enough, when I changed the processor type from
Pentium-Pro/Celeron/Pentium-II
to
Pentium-III
(which is the type of processor in the machine) it works.
