Re: Help with issue with mpt(4) driver

I have just been experiencing filesystem lock-up with a process in
uvn_fp2, so it may be unrelated to you mpt fiddling... That systems
disks are on ahcisata.

It can withstand builds of the world, but not GraphicsMagick:

struct proc *  ffff fe81 4c8c 1d10
uarea *        ffff fe81 3d6d 5d80
vmspace/vm_map ffff fe81 0f23 2470

PID   LID S CPU     FLAGS       STRUCT LWP *   NAME WAIT

? VNODE flags 0x30<MPSAFE,LOCKSWORK>
v_lock ffff fe81 1427 0280

but I'm not sure what to look for...

Cheers,
