I got recently some squid panics where the machines freezed accusing calcru 
went backwards too. This happened on amd64 with sources from first week of 
may. I got it on 20-30 days uptime untouched smp dual-core amds and two 
opteron server. On all of them acpi-fast seems to be the counter. Anyway I 
did a cvsup and haven't seen the problem again so far. I did't get any 
message before, the first caused a panic and funny all panics happened almost 
the same hour last friday.
