>Description:
	My laptop, Panasonic CF-R5 suspend and resume fine with but wireless
	LAN (wpi) disappers after suspend/resume.

	* After suspend/resume it become unusable.
	* After that, wireless LAN interface wouldn't come back untill
	  completely power off.  Even if Windows can't detect wireless LAN:

		1. Boot NetBSD.
		2. Suspend NetBSD
		3. Resume NetBSD.
		4. Reboot the system; shutdown -r now
		5. Boot Windows from boot selector.
		6. Windows can't detect the wireless LAN.

	With lspci command (by pkgsrc/pciutils) and other PCI bus utilities
	dosen't show wpi0 device completely after resume (until power off/on).

>How-To-Repeat:
	Suspend and resume LAPTOP and try to use wireless LAN.

>Fix:
	Unknown.
