[mythtv-users] OT: NTP does not seem to be updating...

[Jeff Simpson]

I spent close to 2 weeks debugging time drift problems and tried
*everything*. The problem turned out to be a harddrive that was not
using DMA transfers.

run "hdparm /dev/hdX" on any/all drives that you are using and make
sure none of them say:

using_dma    =  0 (off)

My problem was that I had onboard RAID that I was using as 4 IDE
channels. Two of them were VIA and the other two Promise. I only had
the Promise driver in the kernel, so drives that were connected to the
VIA channels were running without DMA support. Once I added that
driver, I was gold.

Hope this helps!
