FYI, with a more recent kernel, compiled with -O -pipe (I want to get the kernel stack frame, while on -CURRENT the default is -O2 -pipe -fno-strict-aliasing which will sometimes corrupt it), seems that the panic vanished... (I have tried -c 2000 and -c 4000 and parallely two -c 2000). Right now I am not sure whether Jeff's recent VFS work has contributed to this (hope this is the case :-), or maybe the -O vs -O2 was the culprit (since the scheduler panic vanished away as well :-(. I will try to investigate more on the two issues in the upcoming two days.
