Oops in e100_up

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).
