No ttyS0 interface with new kernel

[chemary]

Hello,
I spent the whole day updating my sheevaplug, now I have kernel 3.9.9 from http://www.xilka.com/kernel installed without problems, and "U-Boot 2012.04.01 (Jun 01 2012 - 02:27:06)" I got it working after trying several environment variables for booting from USB.

But I found that after updating to last kernel I have lost the serial console via the miniUSB, when control is passed to the kernel I don't get messages anymore

$this->bbcode_second_pass_code('', '

These is how uBoot is configured:
$this->bbcode_second_pass_code('', '
baudrate=115200
bootcmd=${x_bootcmd_kernel}; setenv bootargs ${x_bootargs} ${x_bootargs_root} $(x_bootargs_net); ${x_bootcmd_usb}; ${x_bootcmd_sata}; bootm 0x8000000;

x_bootcmd_kernel=usb start; ext2load usb 0:1 0x8000000 /uImage
x_bootcmd_sata=ide reset;
x_bootcmd_usb=usb start;
')

I compared dmesg with the one from the old kernel (2.6.39.4) and I see that previuosly ttyS0 was found and console enabled but I don't see these messages now
$this->bbcode_second_pass_code('', '
Serial: 8250/16550 driver, 2 ports, IRQ sharing disabled
serial8250.0: ttyS0 at MMIO 0xf1012000 (irq = 33) is a 16550A
console [ttyS0] enabled
')

$this->bbcode_second_pass_code('', '
Serial: 8250/16550 driver, 2 ports, IRQ sharing disabled
')

I have the serial devices on dev and inittab seems correct
$this->bbcode_second_pass_code('', '
root@nohost:~# ll /dev/ttyS*
crw-rw---- 1 root tty 4, 64 Jul 6 22:51 /dev/ttyS0
crw-rw---T 1 root dialout 4, 65 Jul 6 22:51 /dev/ttyS1

root@nohost:~# cat /etc/inittab |grep ttyS0
T0:12345:respawn:/sbin/getty -L ttyS0 115200 vt100
')

I don't know if it's a configuration error or maybe the kernel is not compiled for having a serial console (I doubt it).

I tried also to configure netconsole without luck, even monitoring udp trafic and forcing kernel messages I don't see any traffic.

We don't support kernels that aren't ours.
