Re: Repeated panics in bge(4)

Matthias Scheler kirjoitti:

my NetBSD-current system crashed the second time today with a panic
looking like this:

fatal double fault in supervisor mode

This is like my problem except that I have wm(4).

Looks like we are both using NFS, in my case the crashing host was NFS client (NetBSD/amd64 4.99.73) mounting /home from another NetBSD/i386 4.99.73 host. My NFS server is stable, no problems at all...
