maybe an ext4 problem
At boot, with a kernel compiled with support for locks, kmemcheck and so, I got
this from time to time (amoung several other problems reported from kmemcheck
and sometimes a total freeze at boot):
kjournald starting. Commit interval 5 seconds
EXT3-fs (sda1): using internal journal
EXT3-fs (sda1): mounted filesystem with ordered data mode
ADDRCONF(NETDEV_UP): eth0: link is not ready
uli526x: eth0 NIC Link is Up 100 Mbps Full duplex
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
