As of right now, all _known_ block bugs should be fixed in the stuff I
just pushed out, with the current top-of-tree being the merge of the
IDE CD endless loop issue and the NULL ptr oops at elevator change
time:

     Merge branch 'for-linus' of git://git.kernel.dk/linux-2.6-block

    * 'for-linus' of git://git.kernel.dk/linux-2.6-block:
      ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd
      block: don't propagate unlisted DISK_EVENTs to userland
      elevator: check for ELEVATOR_INSERT_SORT_MERGE in !elvpriv case too

but maybe yours is something else.

That said, that udevd message of yours would imply a full root
filesystem, which can cause any amount of issues at boot time..
