Public bug reported: I have a ASUS A7N8X-E Deluxe motherboard with nvidia nForce2 chipset.
The symptom I had was a huge clock drift (many minutes for one hour) and VLC video streaming (my ISP free.fr distributes TV with VLC on their neitwork) worked only a few minutes before image freezes with messages like "main warning: late picture skipped (2732961) main warning: computed PTS is out of range (2596547), clearing out main warning: timing screwed, stopping resampling main warning: PTS is out of range (2636228), dropping buffer main warning: output PTS is out of range (2617423), clearing out main warning: PTS is out of range (2612287), dropping buffer main warning: PTS is out of range (2588313), dropping buffer main warning: PTS is out of range (1304194), dropping buffer ts warning: discontinuity received 0x9 instead of 0xf (pid=69) ts warning: discontinuity received 0xe instead of 0xb (pid=70) ts debug: PATCallBack called ts debug: PMTCallBack called main warning: vout synchro warning: pts != current_date (-2759978) main warning: PTS is out of range (1292834), dropping buffer" see another post of that problem here (sorry, in french) : http://www.freeplayer.org/viewtopic.php?t=5125&view=previous&sid=c77b29c1edcaaf99cc1161565fe5575d and here : http://forum.ubuntu-fr.org/viewtopic.php?pid=699248 I found a workaround by appending "noapic nolapic" to the kernel boot options.
