Kostik,
Looking good after applying your patch and rebuilding the kernel. I've
been exercising the machine for a couple of hours under the same load
which crashed it in short order yesterday.
I will report back if any problems appear.
Thank you for your help!
Regards,
-Chris

The file structure in the dump is fully initialized. It seems that the
issue is with devfs replacing file ops vector with devfs-specific one
in devfs_open() before the struct file is fully initialized in vn_open.
Please, try the patch below (against 7) and report results.
