Are these bad for us?
Those three are from the first boot:

CODE

Alignment trap: keylaunch (3398) PC=0x40239de0 Instr=0xe5102004 Address=0x0001abd5 FSR 0xc2cc3013
Alignment trap: keylaunch (3398) PC=0x402398d4 Instr=0xe5112004 Address=0x0001abd5 FSR 0xc2cc3013
Alignment trap: gpe-confd (3443) PC=0x401c6ff0 Instr=0x15820000 Address=0xbedc045b FSR 0xc2cf7813

gpe-mini-browser also triggers gadzillions of these

Hi,
please also file a bug report about that. We should figure out how to get rid of them. At the moment I have no clue about how to fix it. But I try to find a solution.

best regards

This seems to be an ARM-related problem, so I guess this affects other ARM platforms as well.
It sounds like this /only/ affects performance.
Fixing this may require non-trivial changes to the source code of the concerned applications.
