I'm running FC3 w/ the latest updates (as of yesterday afternoon ;-) on an IBM Think Centre 8187-KU. This machine has a 3G Pentium 4 w/ hyperthreading. After the machine has been running for some number of hours, probably more than 6, the clock stops ticking. I'm running the SMP kernel:
root@Doramichan ~]# uname -a
Linux Doramichan.sanjose.ibm.com 2.6.9-1.681_FC3smp #1 SMP Thu Nov 18 15:19:10 EST 2004 i686 i686 i386 GNU/Linux
[root@Doramichan ~]#
Here's the tail end of /var/log/messages:
Nov 23 03:49:04 Doramichan kernel: Losing too many ticks!
Nov 23 03:49:04 Doramichan kernel: TSC cannot be used as a timesource.
Nov 23 03:49:04 Doramichan kernel: Possible reasons for this are:
Nov 23 03:49:04 Doramichan kernel: You're running with Speedstep,
Nov 23 03:49:04 Doramichan kernel: You don't have DMA enabled for your hard disk (see hdparm),
Nov 23 03:49:04 Doramichan kernel: Incorrect TSC synchronization on an SMP system (see dmesg).
Nov 23 03:49:04 Doramichan kernel: Falling back to a sane timesource now.
Nov 23 03:49:04 Doramichan sshd(pam_unix)[4073]: session opened for user emader by (uid=0)
(I rebooted the machine into the non-SMP kernel, and it's been up now for over 22 hours and still knows what time it is!)
Anybody have any idea what's going on here?
(I have text files w/ the last 150 lines of /var/log/messages, the output of dmesg, lsmod and lspci, Xorg.0.log and modprobe.conf which I'm not including this time in case they make the message too big for the list...)
