I have had this system for about 6-8 months (maybe 10) now. It was originally a Asus A8N-SLI Deluxe with a 3200+ Athlon64. In November I changed to a Asus A8N-SLI Premium, and added another 1GB memory (now have 2GB memory). In all that time I have not had any issues with lost ticks, but I was hesitant to get a X2 processor due to the issue that some people had. Beginning February I got an Athlon64 X2 3800+ processor, and since that time I have also had no issues with lost ticks. I usually run latest git kernel +/- a week. No extra patches, except I started using Alan's libata PATA stuff a week or so back as well. Only difference I can see that might be of consequence, is: 1) Board type? Not sure if anybody with an A8N-SLI had any lost tick issues ? 2) I do not use MD RAID1, but have 2 ST380013AS striped with device-mapper's stripe module. 3) If I remember correctly, then I have the 2 hdd's on nv_sata ports 3 and 4, with ports 1 and 2 disabled, else they show up as sdc and sdd. Not sure if its an A8N-SLI only peculiarity, and not 100% sure of the port order - I can check if it might be an issue? 4) I do not use the NV lan adapter, as I had issues back when I got the system, but rather the extra Marvell controller (skge module). I think it picked up fine, etc, but it lost connection after a minute or two. 5) I run the processor at 240FSB (or HT or whatever) with the memory at 333 (166 on some boards) multiplier (ending up at running 200Mhz anyhow). Not sure if this might make any difference, but just listing it in case. 6) Haven't checked if this makes any difference, but the board have an option for ACPI 2.0 support, which I have enabled. If anything might be of relevance, or you want me to try something, just say it. Same with extra info that might be needed.
