Re: dom0 panics when domU writes to disk on NFS

I'm running a 5.1 dom0 and trying to install a 5.1 domU. The domU's disk lives on NFS and whenever domU tries to write to the disk, dom0 panics.

Any ideas about this?

I've tried to look at the code myself, but I have absolutely no idea what
I'm doing, unfortunately. :-(

(Maybe I should just set up kgdb and do some more digging. I might even
learn something...)


It's an old problem, most probably related to v->p translations in pmap(9).

To inspect the matter, you have to be familiar with x86/xen pmap. Feel free to ask if you want some help with it; unfortunately, you won't have much activity in the upcoming week...

Merry Christmas :)
