Hi Mark,
I think you pin-pointed one of the possible reason of the unknown freeze.. which is FB
mode. Yes, I am using FB mode.. hm.. I will go back to recompile my kernel without FB
mode and see whether this method can fix my problem or not.
You are right for the other assumption, I am running the harddisk in UDMA w/32bits
mode. Are you suggesting me to turn off both functions? But if I turn them off, the
performance will decrease alot.
Is there any way I can get any crash information? e.g. any function I can turn on for
logging or something?
Thanks for your reply..
Best Regards,
Jacky Liu
