I ran into this as well.  It happened with the Alan Cox 14 patch to
Linux kernel 2.4.9 when I installed a fiber channel driver (which added
partitions).  I patched up drivers/block/genhd.c to detect and break
circular links in the partition link list, and also to refuse to add
entries that where already in the list (which was successful, though not
recommended).  Next I used a plain kernel without the AC patch, and
again the problem went away.

Are you using an otherwise unpatched kernel?
