Having the same problem here. It used to work, but now it stopped working. I reboot so rarely that who knows what change may have caused this :P
jowagner, your solution didn't help. As I said, it used to work, so obviously I have nfs stuff installed.
Here is my fstab:
/dev/sda2 / ext3 acl,user_xattr 1 1
/dev/sda3 /home ext3 acl,user_xattr 1 2
/dev/sda1 swap swap defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
10.61.26.66:nb /mnt/nb cifs user,credentials=/etc/samba/.smbpasswd 0 0
jade:/vol/users /mnt/users nfs defaults 0 0
It used to be that the cifs and the nfs shares were mounted on boot, but now they're not.
When I look in dmesg, here's the relevant section

It ends there.
Any help appreciated!
