Hello @Tyler Thank you for your comments.
>>In my opinion, a machine freeze is not likely to be caused by these I am trying to coorelate the events which happen in syslog during time my machine freezes and i have to reboot. See example log from syslog and note the timings May be its not related to my issue with freeze , am trying to zero down the possible issues. Thanks again. Should i post on other bugs you mentioned ?
