Got an 860 a couple of weeks ago after a few years w/5500. Running rc9.1 and its quite awesome. This is what I've been looking out of a handheld . . more of a micro laptop. Great work. Now I was humming along when I had a firefox induced lockup (out of memory?) and after that/ when I'd suspend, the clcok/date would reset to the install date X input would lock up and I'd have to remove the battery to restart.
Searching the forum makes this sound like a consistent prob across RCs. Lots of suggested tweaks to apm but nothing worked for me. Googling lead to a zdebian tidbit about the hardware clock and sethwclock. After removing the battery/ it appears the hwclock is reset and date --set doesn't modfy that. After a crash/battery removal, I was doing date --set and all seemed fine but on a suspend, when the z woke up, X would check the hw clock in some fashion (now reset b/c of battery pull) and it must be comparing the time to the time on some lock file/or something. Current time in hw is now earlier than lock file time and I'm guessing X fraks and game over.
After a battery pull, I've done date --set then sethwclock and suspend works normally and without issue once again
Hope this helps . . cheers Keith
