I'll look into those config settings. While we are talking about config settings, i noticed i had CONFIG_VT turned on. I do the make ARCH=ppc xconfig but i cannot find the setting where CONFIG_VT gets turned on. I don't want to use the virtual terminal & i believe since the kernel is getting configured with CONFIG_VT=y, it is trying to mount tty0 which is not part of my root file system. Does that make sense?? Is CONFIG_VT dependent on some other config setting?? How do i get CONFIG_VT set to n?? thanks pankaj

I saw all the usual NFS Lookup calls like /lib, /ld- <http://2.3.1.so> 2.3.1.so ..... /libc- <http://2.31.so> 2.31.so The last NFS lookup call looks like DH:0xbea72a4a/tty0 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 ?? What should be the next NFS Lookup call? 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. http://ozlabs.org/pipermail/linuxppc-embedded/2004-August/015250.html <http://ozlabs.org/pipermail/linuxppc-embedded/2004-August/015250.html> Thanks pankaj -----Original Message----- From: [EMAIL PROTECTED] [mailto: <mailto:atul.sabharwal at exgate.tek.com> atul.sabharwal at exgate.tek.com] Sent: Tuesday, February 28, 2006 6:03 PM To: Patil, Pankaj P. Cc: linuxppc-embedded at ozlabs.org Subject: RE: INIT: Easy answer is do you have /dev/console in your file system. Glibc opens /dev/console and the kernel uses /dev/ttyS0 as specified on the command line. There should not be any app calling uart_close as the console deriver should be opening it. -- Atul Hi, I am running u-boot & linux2.6.12 on a custom ppc board(functional HW). I can get to the point where u-boot loads the kernel, kernel does all the initialization, loads the Root File System over NFS & calls the Init process. Next, i am expecting to see a shell prompt. I am not sure where in the Init process i am failing. I have written my own serial driver(Philips SC28L194 Quad UART--under development-possible culprit). The printks work just fine. All i see is the kernel calling the Init process & after a minute or so i see uart_close call. The kernel runs just fine & responds to ping. What can trigger a uart_close??(tty_release calls release_dev calls uart_close) I have a JTAG debugger. What's the best way to debug once Init process is running??
