Hello,

I am new to this group, so first of all I would like to thank all the
people here for the help you provide.

I have a TS7300 board that comes with 2.4 kernel by default. I have
downloaded the 2.6 kernel binary from the web and stored in the sdcard
with the command:
$ dd if=zImage-72xx-2.6.21-ts of=/dev/sdb1
I have also downloaded the Debian distro for 2.6 kernel and copied in
/dev/sdb3 partition.

The system boots, but when it tries to access the nfs server, it
automatically reboots. I downloaded the sources and compile the kernel
applying the same config, but changing the kernel command string to
avoid the nfs boot. It makes the same.

My kernel command string is:
"console=ttyAM0,115200 root=/dev/ram0 init=/sbin/init"

The output just before reboot is:
...
RAMDISK: ext2 filesystem found at block 0
RAMDISK: Loading 3072KiB [1 disk] into ram disk... done.
EXT2-fs warning: maximal mount count reached, running e2fsck is

I don't know so much about ram devices. Any help will be appreciated.
Thank you very much for your time and effort.
