Very often I see vista gets hung loading crcdisk.sys while booting system in safemode/non-safe mode

Connecting windbg and looking at stack trace shows this:

0: kd> kn

The current workaround to get across this hang has been to hit a “g”, kill
windbg and restart fresh windbg session. “Just hitting go” doesnt seem to
help.
Has anyone see similar problem? Does anyone know the problem/solution apart
from this workaround?
