Your locking and rman changes to pci/if_*

[Ruslan Ermilov]

Nate,

Your "Clean up locking and resource management for pci/if_*"
commit made my machine panic whenever I detach the Xircom
CardBus:

: dc0: <Xircom X3201 10/100BaseTX> port 0x1000-0x107f mem 0xd8000-0xd87ff,0xd8800-0xd8fff irq 11 at device 0.0 on cardbus1
: dc0: Ethernet address: 00:10:a4:c0:c0:45
: miibus0: <MII bus> on dc0
: tdkphy0: <TDK 78Q2120 media interface> on miibus0
: tdkphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
: tdkphy0: detached
: miibus0: detached
: dc0: detached
: panic: blockable sleep lock (sleep mutex) Giant @ vm/vm_fault.c:206

Reverting to if_dc.c,v 1.96 makes the problem go away.
Please fix.


Cheers,
