Hi so I`ve played with it again, and results are strange. Regardless if HPET is enabled or not.. FreeBSD with atapicd kldloaded won`t mount /dev/acd1 (mounting /dev/cd0 works). When I tryied to mount acd0 it still hangs at READ_BIG TIMEOUT. When I left CD in drive, and rebooted (I wanted to switch HPET), it freezes on cd0 initialization with READ_BIG timeout (I think it`s causing GEOM_LABEL module trying to read CD label). So I think that disabling GEOM_LABEL would help a little. I`ll try on friday with another SATA DVD drive if it`s not a bug inside firmware of LG :) . Best regards, Jan Jeremy Chadwick napsal(a): > On Wed, Nov 19, 2008 at 03:24:40PM +0100, Jonas Lund wrote: >> (NOTICE: i'm more of a lowlevel guy close to hardware guy not knowing >> much of freebsd internals) >> >> The fact that FreeBSD is NOT using HPET for timing might be the answer >> to the "mystery".
