Subject: udev going crazy in 2.6.19-rc6-mm1

udev seems to be going nuts in 2.6.19-rc6-mm1, adding and removing 
/dev/md0 and using a ton of CPU. This with the versions in both Fedora 
Core 5 and 6. This doesn't happen in older kernels, the last one I 
tested was 2.6.19-rc3-mmsomething. If I kill udevd and start it again it 
seems fine then. Some kind of feedback loop perhaps?

Here is some output from udevmonitor:

udevmonitor prints the received event from the kernel [UEVENT]
and the event which udev sends out after rule processing [UDEV]
