Subject: Re: kern/32035: UP ACPI kernels lose time
Date: Tue, 14 Mar 2006 18:12:40 +0000 (GMT)

  	I'm also seeing a similar affect (clock losing minutes per hour),
  	and ntp unable to cope, on two single proc machines, but only
  	when an ACPI kernel is run.
 
  	diff between working (noacpi) an non working (acpi) kernels below.
 
  	I wonder if ths could in any way be related to port-i386/32953
  	(Repeated keystrokes under X using APCI kernel)
