nfsroot w/ smp 2.6.7 on ultra2 bug report

[Stephen P. Becker]

Hi,

I have an Ultra 2 with dual 200mhz ultrasparc I processors.  I had been 
trying to run nfsroot with kernel 2.6.7 on the machine, and could not 
get it to work:

IP-Config: Guessing netmask 255.255.255.0
IP-Config: Complete:

On a suggestion from Ciaran McCreesh, I recompiled my kernel without SMP 
support, and was able to mount nfsroot with no problems at all.  I also 
successfully compiled and booted a 2.4.27 smp kernel with nfsroot, and 
had no such problems.
