I'm going to try running with the cpus=1 flag and see how that works out. From what I gather it might well be attributed to a timing issue between the two cores, so rather than use idlehalt flag I'll see how this pans out.

cpus=1 is very stable for me.
It's not ideal though if I you can't use both cores. I can barely play 720p with one core only. As for the multiplicator, if I change it to 10.5 what else do I have to adjust as my system does not POST on this setting. FSB is at 200 and LDT/FSB freq ratio is on Auto. I have a 4200+ X2. |
It is perhaps depending on the mouse resoulution? My pointer speed is set at the third marker from the left, but I need only 2 x 2 cm to span the 1600 x 1200 pixel screen size. Don't know which resolution my mouse has, maybe 800 or so. It's an optical mouse.

@ Rogue, i am inclined to agree it must be a timing issue - seems everyone who has experienced this problem are all running x2 processors. |
I have an Opteron 185, it's a also a Dual-Core cpu, it's working perfectly, no mouse problems. I even use it overclocked from 2,6 Ghz to 2,86 GHz, still no problems.
Do you have the mouse problem already in the installation DVD or in safe mode (boot with -x). Maybe it's a gfx driver problem. I also have deleted all GeForce, NVDA* and other ATI gfx kexts except my RadeonX1000 kexts. |
My machine has now been up for well over 12 hours without any sign of the bug. Last night I was working in Photoshop without a hitch and after leaving the machine on over night it's still running along quite happily. I'm wondering if certain apps that use SMP are causing the problem - more specifically third party apps. I think it's safe to assume that this is not a 'mouse bug' per se, but a timing issue between the two cores making the system skip and stutter and the mouse pointer to freak out. I'll keep on testing and report back in later.

Could you tell me your bus frequency and the multiplicator settings? Mine is actually 220 MHz, Multiplicator 13x, Vcore 1.3125 V. I'll test the settings you have when you post them. But I presume you both thave an Athlon 64 X2 processor which have 2x 512K Level-2-Cache. The Opteron series and the FX-60 (Socket 939) have 2x 1MB L2-Cache. I phoned with the AMD support and they said they're replacing the missing 512K with 200MHz more bus frequency.
Was a great game yesterday, Germany-Portugal. I'm no big soccer fan, but it was good for me: I got a 7 Euro Paypal-Coupon from ebay 'cause we're in the semi-final :-D |
Voyn1x, we have the same CPU, hence I don't believe the mouse stuttering problem is related to Dual Core. Actually I can remember that I had this problem a long time ago, when I was starting with OSx86. I think it must be due to (driver?) incompatibilities because apparently I didn't experience this problem for months, since my machine is configured fine.
Tell me what I shall do to test whether I really don't have the problem - which tasks shall I run? I use a lot of resources of my machine and most of the time got it running for several hours. |
@naquadda,
I'll be able to give my bios settings tomorrow, i'm away from my hack until then :) @Puttabong, Try running some heavy filters in photoshop, or do something cpu intensive. The problem doesn't normally appear until at least 10hrs+ have passed. You'll notice it most if you try to drag a window around, you should see it jump about. Leave Firefox open and see if it quits with a 'divide by zero' error at all, it normally quits every couple of hours for me. Eventually you should start to get the 10810 error which is only fixable by logging out and back in again. I believe this is all related to the mouse bug since all of these issues are solved if i you boot with cpus=1. |
to add, when using cpus=1 my system was up for 2 weeks with no reboots or errors of any kind.
