Oops in e100_up

Oops in e100_up

[Gerrit Renker]

With the davem-2.6.24 tree I get the following Oops in the e100 driver (cribbed from console):

Code: 6c ff ff ff 8b 48 0c ba 01 00 00 00 89 f0 e8 1b f2 ff ff c7 86 9c 00 00 00
      01 00 00 00 e9 4e ff ff ff 89 d0 e8 b3 f8 0b 00 eb 8e <0f> 0b eb fe 55 89 e5
      56 53 83 ec 0c 8b 98 dc 01 00 00 e8 ff b9

EIP: e100_up+0x11d/0x121 

SS:ESP 0068:f759ce38

Stack: syscall_call -> sys_ioctl -> vfs_ioctl -> do_ioctl -> sock_ioctl -> inet_ioctl -> devinet_ioctl ->
       dev_change_flags -> dev_open -> e100_open -> oops

The system log then goes on reporting "eth0: link up, 100Mbps, full-duplex" and hangs while trying to
restore the serial console state (not sure that this is related).

Probably the NAPI conversion, I'll try to get to diagnosing this
one soon but I've been wrapped up in some other tasks so if
someone could beat me to it that'd be great :-)

restore? Is this during resume from suspend or something?

This seems to have been fixed by a bug reported by akpm and fixed by
Thomas Graf, check a recent post with "netconsole" on the subject.
