Ok, I now have 1.1.3 installed and the following setting cause the
problem:

  PWR_CLOCK_AC=0
  PWR_CLOCK_BATTERY=2

as well as the default values (both empty) of course.

The following settings work fine and make the problem disappear:

  PWR_CLOCK_AC=1
  PWR_CLOCK_BATTERY=2

  PWR_CLOCK_AC=2
  PWR_CLOCK_BATTERY=2

So to be on the save side, I suggest for the EeePC 4G (aka 701) to
either disable SHE or use the 1+2 setting as default.

I'm currently not at home. When I'm back at home, I'll upgrade the
BIOS from 0901 to 1302 to see if the problem still persists. If it
doesn't persist, a BIOS version check could be done to check for BIOS
versions below 1302 to enable safe settings.
