I do have /dev/console in my file system. In fact , i used ethereal on the host to see how far the INIT goes.<br>I saw all the usual NFS Lookup calls like /lib, /ld-<a href="http://2.3.1.so" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
2.3.1.so</a> ..... /libc-<a href="http://2.31.so" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
2.31.so</a><br>The last NFS lookup call looks like DH:0xbea72a4a/tty0<br>There
are bunch of read replys after that but no more NFS lookups. Is it
normal to see a NFS Lookup that looks like 0xbea72a4a/tty0 ??<br>What should be the next NFS Lookup call?<br>I
did some searching from previous posts but haven't found exactly what i
am looking for. I am attaching a link to something that looks similar
to my problem. Just in case, someone's having trouble understanding my
issue.<br><a href="http://ozlabs.org/pipermail/linuxppc-embedded/2004-August/015250.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://ozlabs.org/pipermail/linuxppc-embedded/2004-August/015250.html

linux2.6.12 on a custom ppc board(functional HW).<br>I can get to the point where u-boot loads the kernel, kernel does all<br>the initialization, loads the Root File System over NFS & calls the<br>Init process.<br>Next, i am expecting to see a shell prompt. I am not sure where in the

<br>i see uart_close call.<br>The kernel runs just fine & responds to ping.<br>What can trigger a uart_close??(tty_release calls release_dev calls<br>uart_close) I have a JTAG debugger. What's the best way to debug once
