I've seen this warning on 2.6.29-rc3 when I removed a iSCSI device without
unmounting a filesystem on it:
Block device has just burned under filesystem's feet (blkdev return
EIO for all requests.) What are you expect in this condition?

Ask someone not familiar with kernel internals which message tells more:

    WARNING: at fs/buffer.c:1250 mark_buffer_dirty+0x7c/0x90()

or:

    WARNING: Block device has just burned under filesystem's feet


As soon as i understand your systems is alive without any BUG or OOPS.
The only consequence is big-bada-boom message which is IMHO quite right.

The "big-bada-boom message", "---[ cut here ]---" don't explain what happened, but rather "indicate a major problem" (as it's printed by kernel/panic.c).
