RE: clock drift?
There are a couple of issues with older kernels that causes clock drift:
1. Under high interrupt load some timer ticks could be lost. In some
rare cases this even caused the watchdog to bite. This was fixed
just after 2.4.14. Check in include/asm/irq.h if there is a
BUILD_TIMER_IRQ macro. If not you have this problem.
2. The normal timers in ETRAX runs 64ppm too fast. This has been
fixed after 2.4.16.

Subject: clock drift?
I'm woundering if anyone but me has experienced substantial system
clock drift with devboard_lx? I've had reports of the system time being
several hours off after just a couple of days uptime. Some drift I
expect since I'm not using NTP but several hours? Anyone has an idea?
P.S. Kernel 2.4.14 used.
