Im running daily-build now, so cant go back and check, but those messages have been there as long as I can remember. Can you confirm that the Alix actually has a Geode ? if not, then the clocksource business above isnt relevant. root@voyage:~# more /proc/cpuinfo processor : 0 vendor_id : Geode by NSC cpu family : 5 model : 9 model name : Unknown stepping : 1 cpu MHz : 266.667 If it is a geode, please try daily-build, then we can closely compare your dmesg to mine. > >> root@voyage:~# uname -a >> Linux voyage 3.4.4-voyage #1 SMP PREEMPT Sun Aug 12 12:01:41 HKT 2012 >> i586 GNU/Linux >> So youre hanging ? and not spontaneously rebooting ? > > it hangs on PXE boot. > >> there was a problem with 0.8.0 or 0.8.5 relating to contents >> of /etc/modprobe.d/4801.conf, a missing "options". >> Heres a correct one. >> >> # These lines generated automatically by copyfiles.sh, >> # parsing VOYAGE_SYSTEM_MODULES from Profile: 4801 >> # on Tue Aug 14 21:18:56 MDT 2012 >> # >> >> options wd1100 sysctl_wd_graceful=0 sysctl_wd_timeout=30 >> options scx200_acb base=0x810,0x820 >> options pc87360 init=2 >> >> can you C&P the console msgs ? > >============================= > boot: 3 > Loading linux.... > Loading initrd.img........ready. > [ 0.000000] Linux version 3.2.17-voyage (3.2.17-1) ... > enabled, doesn't support DPO or FUA > [ 2.543017] Switching to clocksource tsc _______________________________________________ Voyage-linux mailing list Voyage-linux@list.voyage.hk http://list.voyage.hk/mailman/listinfo/voyage-linux
