Wow! That was fast!
I a= pplied the patch and it worked very well. Now I can use the commands normal= ly.
I will be doing more tests in the next days, but it seems that my prob= lem is solved.

Is this patch already mainstream in newer kernel versions?

Thanks again,

Hi

Hello all,
I'm working with an MPC880 board that is supposed to run linux-2.6.32. =
After
some work, I could get the kernel up and running, mounting a rootfs via
NFS.
The problem that I'm facing now is that when I try to run any process (=
may
be an ls, cat, or whatever), the response of the process is *very* slow
(something like 10 to 20 seconds for a ls).
Monitoring the network packets, I can see that the nfs protocol is exchange=
d
just fine, but at some time it simply stops, starting again with a request
from the board several seconds later.
I'm thinking that the processor is running (something, I don't know=
 what)
for all this time before I can see requests coming from the board again. I
pinged the board from the PC and during all this I can see the packets bein=
g
answered.
Can you try this patch?

 
My question to all is, did anyone see something like this alread=
y? Besides
that, what is the status of the linux kernel support for the 8xx platform?
Is it being actively tested / used today? I ask this because it seems that
all the information on the internet very aged (forum discussions from 2005
and below mostly).

Is there something that I can do to try to narrow the cause of the problem?

Anyway, any help would be truly appreciated. Please excuse me if this is no=
t
the right place to ask this too.

Thanks and best regards,
