Hello,
I have a strange problem on Ultrasparc III Cu processor system. There are 2 CPUs in this SUN 280R. I have tried different kernels (2.4.21, 2.4.22)
The problem is, if I request date and time of the system I get different answers. It seams, that there is a syncing problem between the hardware and the system clock.
# hwclock --set --date="9/24/03 10:56:00" # hwclock Wed Sep 24 10:56:03 2003 -0.232462 seconds # hwclock Wed Sep 24 10:56:06 2003 -17180.423522 seconds # hwclock Wed Sep 24 10:56:09 2003 -0.637757 seconds
# date Thu Sep 25 06:05:13 CEST 2003 # date Thu Sep 25 01:18:53 CEST 2003 # hwclock Wed Sep 24 10:57:52 2003 -17180.702994 seconds
In the system there are two equal cpu's. cpuinfo shows two different CpuBogo's.
# cat /proc/cpuinfo cpu : TI UltraSparc III+ (Cheetah+) fpu : UltraSparc III+ integrated FPU promlib : Version 3 Revision 5 prom : 4.5.21 type : sun4u ncpus probed : 2 ncpus active : 2 Cpu0Bogo : 1599.07 Cpu0ClkTck : 0000000047868c00 Cpu1Bogo : 1.63 Cpu1ClkTck : 0000000047868c00 MMU Type : Cheetah+ State: CPU0: online CPU1: online
I think the date, time problem can be a bug in the RTC-module.
