MTD crash with kernel 2.6.13

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): http://www.dave-tech.it/download/misc/sw/zefeer/zelk/mtd/

Anybody experienced the same problem? Any suggestions about how to solve it?

Thanks in advance,
llandre
