closing the loop on this. it looks like the panic was due to debugfs
being mounted on my system. debugfs is part of the drm-next-kmod port
which enables i915 gfx on recent intel GPU's, and debugfs doesn't *need*
to be mounted but is quite useful and fun to play with.
I updated an amd64 system last night to r327979 and it panics into gdb
after rc attempts to mount local filesystems.
The panic line is:
Fatal trap 12: page fault while in kernel mode
gdb states that it stopped at:
Stopped at prison_allow+0x4 movq 0x30(%rdi),%rax
Is this a known issue? This is my primary workstation - so I'm going
to revert back to an older kernel, but if more info is needed I can
put some cycles into debugging today.
anywho - the fix on my end is to:
- remove the drm-next-kmod port/pkg
- build and install latest kernel+world
- reboot and build/install the drm-next-kmod port/pkg
- reboot and enjoy i915 graphics
i'm kinda interested in what prison_allow does now as i haven't run
across it before. is this part of the jails infrastrucutre?
