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??

I am attaching a dump of my console:
