[Cbe-oss-dev] intermittent trouble on startup on a QS22 with 2.6.30

[Marcus Daniels]

Hi,

I'm trying to get a 2.6.30 kernel up on a QS22 (Triblade environment), 
and I've been having intermittent problems like below (pasted from 
`rcons').  Any ideas?

DHCPREQUEST on eth0 to 255.255.255.255 port 67
DHCPACK from 11.20.0.1
bound to 11.20.6.3 -- renewal in 16962 seconds.
Setting up nfs with ram overlay.
mounting 
mn-asds4:/install/netboot/fedora8/ppc64/celldev_mdaniels/rootimg on /ro
aufs test_add:242:mount[1183]: uid/gid/perm /ro 0/0/0755, 0/0/01777
