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

EIP: e100_up+0x11d/0x121

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).

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.
