Problem Description: mounting a network share with mount.cfis gets an error about the server not responding. Modifying the mtu of the ethernet interface make it to work.Steps to reproduce:
mount.cifs \\ntinstall\install /z -o "username=guest,ro,nocase"
An error on the Screen:
--------------------------------------
CIFS VFS: server not responding
CIFS VFS: No responde to cmd 46 mid 10
--------------------------------------
execute:
ifconfig eth0 mtu 1942

Then the network share is accessible. And the error disappear.
How strange. Good detective work, btw.
Did we a) change the MTU size with 2.6.25 or b) break larger MTUs in 2.6.25?
Can you find out what the MTU size was with 2.6.24? And what size is the MTU in 2.6.25 before you reset it?
Thanks.
