[PlanetCCRMA] Can't use rt-kernel from planetccrma-core

[Filip Hoško]

Hi,

thanks for all your answers, my system specs are -

OS: Fedora 13 Gnome, kernel 2.6.34.6-47.fc13.x86_64 (stock, non-rt that
works well - but with lots of xruns, so it's unacceptable)
laptop: ASUS A6KM Q072 with buggy DSDT table (I have a fixed DSDT, but can't
find a way to implement it into kernel)
graphic card: Nvidia Geforce Go 7300, nouveau driver + mesa dri drivers and
dri drivers experimental installed to make 3D work
wireless: Broadcom BCM4318 with b43 driver
on-board sound card: SiS AC'97
firewire adapter and ext. sound card: Ricoh Co Ltd R5C552 with M-Audio
ProFire 610 (firewire adapter actually works only partially and didn't work
at all in Ubuntu.. It seem I'll have to buy a cardbus adapter with Texas
Instruments chip in order to use my ProFire under Linux..)

This is the output from /var/log/messages after the "hang" -

Then I rebooted again, deleted those parameters "quiet" and "rhgb" and did a
boot with that rt-kernel (while in runlevel 3). Everything went fine until
it stopped at Running Avahi Daemon ..... Failed (translated from slovak) and
system froze. Maybe that Avahi daemon causes the hang?


All the best,

Filip Hoško
