Hello
I have been trying to move accross to the 2.6.37 kernel and have got the system mostly booting except for the network adapter. My board uses the smsc911x driver for the phy. It shows from the boot log that the device is seen but there is no dhcp request. I need dhcp as I develop using NFS. It all used to work nicely with 2.6.32 and I thought transition to 2.6.37 would be relatively painless. How wrong I am.
I have been looking through the forums but I cannot find a solution to the problem.
I have checked and DHCP server is running fine and the NFS server is running fine as I can boot using 2.6.32 kernel and appropriate rootfs via NFS.
I think the kernel boot line is correct: Kernel command line: console=ttyO0,115200n8 mem=71M@0x80000000 mem=384M@0x88000000 mpurate=1000 rootdelay=30 nfsroot=10.0.0.10:/opt/ICU_004 root=/dev/nfs rw rootfstype=nfs ip=dhcp
I added the root delay just in case there was an issue bringing the phy up and requesting an address. I have checked with wireshark and there are no requests.
The boot log is as follows:
Starting kernel ...
Uncompressing Linux... done, booting the kernel.

[ 2.319122] Waiting 30sec before mounting root device...
[ 32.332611] List of all partitions:
[ 32.336334] 1f00 512 mtdblock0 (driver?)
[ 32.341766] 1f01 1920 mtdblock1 (driver?)
[ 32.347106] 1f02 128 mtdblock2 (driver?)
[ 32.352508] 1f03 4096 mtdblock3 (driver?)
[ 32.357910] 1f04 517632 mtdblock4 (driver?)
[ 32.363250] No filesystem could mount root, tried: nfs
[ 32.369110] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,255)
Hopefully someone else out there has had the same problem and solved it.
Thanks
Marc
