Hi all, thanks for suggestions I added rsize=1024,wsize=1024 to CMD LINE. INIT can now be executed from nfs, but I think that the problem still exists, during the start up process ( from when the rootfs is mounted until user get a command prompt ) some times ML403 stops working completely, and generates "Segmentation Fault" and similar messages. some other times the system comes up with no problem.
I had the same problem when mounting rootfs using nfs via 100mbits link , but for gigabit link the probability of reaching this unstable state is much higher. any ideas? thanks ---------------------------------------- > Subject: Re: Kernel 2.6, ML403, rootfs on nfs, gigabit ethernet link, nfs > mount problems > From: [EMAIL PROTECTED] > To: [EMAIL PROTECTED] > CC: [email protected] > Date: Tue, 29 May 2007 10:52:21 -0400 > > Hi Mohammad, > > On Tue, 2007-05-29 at 14:41 +0000, Mohammad Sadegh Sadri wrote: > > Hi all, > > > > well I could bring up the grant's kernel on ml403 completely. the root file > > system was over nfs. > > > > when I use a 100mbits link for connection to ml403 , every thing is working > > suitably. > > but when I use a 1000mbits link, I see that ml403 gets ip address from dhcp > > and mounts the root file system but can not go further , it stops with a > > message: "nfs server not responding ...." some thing like this. > > > > when pinging to ml403 with 64 bytes packets, ping works fine for both of > > 100 and 1000mbits links > > but when I try to ping the board with 4000 bytes packets I notice that > > ml403 on gigabit link can not answer to ping packets, however on 100mbit > > link every thing works just fine. > > > > any ideas? > > NFS is notorious for sending lots of big packets one right after > another. This can easily overwhelm an Ethernet receiver.
