- Very often I see vista gets hung loading crcdisk.sys while booting system in safemode/non-safe mode after a crash
- Posted by Praveen Kumar Amritaluru on February 20th, 2007
Connecting windbg and looking at stack trace shows this:
0: kd> kn
# ChildEBP RetAddr
00 818f1ca8 818d69f4 nt!RtlpBreakWithStatusInstruction

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?

On my systems, crcdisk just happens to be the last loaded boot driver. A
hang at that point is usually not related to crcdisk.
I have experienced similar hangs in the past:
1. When a debugger is attached to the serial line of the hung system, some
times it helps to reduce the debugger's baudrate.
2. On some of my systems, swicthing from COM debugging to 1394 debugging
helped get rid of the boot hangs.
3. Other times one of the boot drivers is really hung. !locks in the
debugger can reveal one of the PnP locks being held by a thread that is
stuck in a driver.
Bottom line is that each hang can be different and has to be figured out
individually. I don't remember to have ever seen one that was related to
crcdisk though.
