I have x86 OpenWRT (kamikaze 8.09) running on Alix 3D2. I found from failsafe mode, the reboot command does NOTHING. Can anyone tell me how to reboot from command under failsafe mode?

Hi.

If sysrq-trigger was compiled into the kernel you can try

echo b > /proc/sysrq-trigger

- this will force a system reset, however it is not very healthy for ext2 filesystems so make sure to issue a "sync" before and run an fsck afterwards.

I can't find sysrq-trigger entry from menuconfig, can you tell me more detail?

Thanks

You can find it in make kernel_menuconfig, magic sysrq keys.
