Subject: [11/11] [VIA RHINE] older chips oops on shutdown
Date: Thu, 10 Mar 2005 15:09:49 -0800 [thread overview]
Message-ID: <20050310230949.GL22112@kroah.com> (raw)

-stable review patch. If anyone has any objections, please let us know.
------------------
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.
