 It looks like the problem is in HPET timer operation. There are number 
 of known and handled problems with AMD HPETs, but seems like you've 
 found new one. Unluckily, the part of the log about HPET timer didn't 
 fit into the message buffer. The buffer can be tuned with tunable 
 kern.msgbufsize. Default value is 98304. You may try to double it. The 
 specified value must be multiple of 4096.
