Hi All, I'm having a strange problem of loosing stdout output over serial console. I'm booting a kernel (3.14.16) on a x86_64 based board with a serial port. The board has Grub and Linux (with a minimal initrd) installed on a SATA HDD and starts linux with the following cmdline parameters from GRUB: console=tty0 console=ttyS0,115200n8 init=/bin/bash Grub loads the kernel fine and I can see the various debug messages on minicom. However, once the kernel starts init (i.e bash), I stop seeing any output. There's no error, no crash anywhere. It just looks like the stdin/stdout of the application (in this case bash) is not connected to the serial console. I'm sure it's a config issue, but I can't fathom what I need to change? Any hints? Thanks, -mandeep
