I can't believe it, light at the end of the tunnel at last!! Must say I've never heard of these flags until now.

Clawhammer, If this works you're a star... :)

* Adds kernel flags and restarts hack *

Thanks ClawHammer! I'm going to try and confirm this when I get back home.

I think it fixed my mouse lag when transferring large files across hd's and such. I only used the notsc flag so far. Does this mean I might actually be able to start using Leo full time?!


Edit: maybe not... Might have to add the other kernel flag. Maybe I am having other issues.....
Well, I just realized that my music stutters too when I have the mouse stutter bug (while transferring large files).. Both kernel flags are added, am I having issues with the ATA kext?

I couldnt read all the stuff written, its too much, but im having the same problem. My hardware:

GA-K8NXP-SLI
A64 3800+ X2 2ghz @ 2.6ghz (260fsb)
4gb DDR 333mhz @ 420mhz

bla bla....

anyway, i opened all the aplications i had and nothing happened, i do think its something related to the net. Anyway ill wait to see your results with the kernel flag and then ill try ^^! ;)

I added four flags to my com.apple.boot.plist and left the machine running over night with several apps running plus a download. In this time frame there have been no 'unexpected quits', -10810 errors or stuttering/lag. I'll keep you all posted.

Do you always use the flag cpus=2 ? I don't use it. Is your system gettin slower by disabling HPET ?

I don't always use the cpus=2 flag, this is just a test. HPET is just another timing method, and no, it's not got any slower.

I presume it's for HyPEThreading. But the option notsc ? I have no idea for this.

HPET stands for High Precision Event Timer. TSC is Time Stamp Counter.

Ah!
