Panic on boot during scan with pmspcv

[Conrad Meyer]

For some reason, it only crops up on UEFI boot. "Legacy" boot "just works."

It looks like we're locking a mutex in a struct at NULL.

(trap)
__mtx_assert+0xdb
agtiapi_cam_action+0x45
xpt_action_default+0xbe3(?)
scsi_scan_bus+0x1cd
xpt_scanner_thread+0x15c
...


Fault is at 0x18.

(kgdb) l *(agtiapi_cam_action+0x45)
0xffffffff806d4ef5 is in agtiapi_cam_action
(/usr/src/sys/dev/pms/freebsd/driver/ini/src/agtiapi.c:1818).

Possibly here?

1814   mtx_assert( &(pmcsc->pCardInfo->pmIOLock), MA_OWNED );

Best,
Conrad
