I am working with the efikamx netbook since october and really like the device. I accomplished to adapt the kernel for 13.1 displays with a resolution of 1366x768 which makes the device even more usable.

Unfortunately, the netbook does not boot very reliably. Since the error has not disappeared by itself, i took a closer look at the serial output and captured the inital booting sequence. I can reproduce the failure by putting a delayed shutdown command into rc.local. After some small number of bootups, the netbook hangs:

Is this a known problem ? Any ideas what to try next ?

regards, Julian
