That was quick :-). Backing out the sysctl_check.c diff gives me a

Michael Cree: could you try backing out the diff below from your
2.6.24-rc3 tree and see if things are now working for you?
Yes (conference is now over). I backed out the sysctl_check patch from
2.6.24-rc3 and, indeed, got a working kernel.
The working kernel (was probably 2.6.24-rc3 less sysctl_check patch, but
might have been a 2.6.23 variant) has the following in /sys/block

I failed to spot any difference (other than the formatting of the dates)
between the two!
