Subject: PR/22493 CVS commit: src/sys/dev/pci
Date: Tue, 26 Apr 2005 07:55:18 +0000 (UTC)

 Module Name:	src
 Committed By:	scw
 Date:		Tue Apr 26 07:55:18 UTC 2005
 
 Modified Files:
 	src/sys/dev/pci: if_wm.c
 
 Log Message:
 In wm_stop():
 
  - Clear the interrupt mask to ensure the device cannot assert its
    interrupt line.
  - Clear sc->sc_icr to ensure wm_intr() makes no attempt to service any
    currently pending or shared interrupt.
 
 This should address the problem reported in both PR/29903 and PR/22493.
 (wm(4) is susceptible to crashing in wm_intr() when the interface is downed)
