Jeff,
thanks a lot for you help. I forwarded your message to David Woodhouse.
I hope this can help to find the bug.

Hi all,
I encountered a problem with MTD with kernel 2.6.13 on ARM architecure.
It crashes in __wake_up_common function when I try to erase a MTD
partition on StrataFlash. I've already talked with David Woodhouse over
#mtd channel and it really seems it is a bug in MTD code (he suggests it
is due to an uninitialized wait queue). I tried to patch the kernel with
latest MTD code but the crash still occurs. Here are available the full
dumps of the console (with and without DEBUG_WAITQ flag):

Anybody experienced the same problem? Any suggestions about how to solve it?
Thanks in advance,
llandre
