Ticket #1 (closed defect: fixed)
kernel is running way too slow

The 18.104.22.168 kernel is running way too slow at the moment. Overal system
performance is about 10% of what is to be expected.
during kernel bootup we clearly see that clocks are configured correctly:
S3C2410: core 202.800 MHz, memory 101.400 MHz, peripheral 50.700 MHz
Calibrating delay loop... 4.39 BogoMIPS (lpj=10976)
Comparison with other S3C2410 systems shows that bogomips should be at about 100
(at 200MHz cpu core clock).
I've already checked SDRAM timings, bus access mode (async/sync) and cache
enabled status without finding a cause for the problem.
