+Hi,
+
+Kernel 2.6.11, hardware is a MSI KT333-based board with an XP1800.
+
+I'm oopsing on shutdown on a machine that has a Via Rhine adapter in it:
+
+Unable to handle kernel paging request at virtual address e0803003

+Seems like it is the ioread8 in:
+
+ /* Hit power state D3 (sleep) */
+ iowrite8(ioread8(ioaddr + StickyHW) | 0x03, ioaddr + StickyHW);
+
+that fails. StickyHW is 0x83. lspci says:
+
+0000:00:07.0 Ethernet controller: VIA Technologies, Inc. VT86C100A
+[Rhine] (rev 06)
+ Flags: bus master, medium devsel, latency 32, IRQ 18
+ I/O ports at ec00 [size=128]
+ Memory at dfffff80 (32-bit, non-prefetchable) [size=128]
+
+In other words, it's trying to read outside of the I/O range (0x80),
+which matches the fauling address.
+
+I'm guessing my chip revision doesn't support WOL, it's a crappy noname
+card.
+
+It does seem as if rhine_power_init checks quirks for rqWOL before
+touching any registers. Should rhine_shutdown do the same? Proposed
+patch below, which resolves the problem on my system.

+
+Check to make sure WOL is supported before setting it up in
+rhine_shutdown.
