           Summary: via-rhine - no network after suspend to disk
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.24.3
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Network
        AssignedTo: jgarzik at pobox.com
        ReportedBy: tch at wpkg.org


I have a network card which uses via-rhine module. After I wake the machine up
after it was suspended to disk, network doesn't work.

dmesg tells this:

NETDEV WATCHDOG: eth0: transmit timed out
eth0: Transmit timed out, status ffff, PHY status ffff, resetting...
via-rhine: Reset not complete yet. Trying harder.
eth0: link up, 100Mbps, full-duplex, lpa 0xFFFF

The only thing which helps is unloading via_rhine module and loading it again -
after this, network works fine again.
