    Subject[11/11] [VIA RHINE] older chips oops on shutdown

    -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
    printing eip:
    c01f262c

    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.
