I had been following the negative calcru discussion with moderate interest until I got a new machine that exhibits the "calcru: negative time" problem. The machine is a 400 Mhz Dell with a Diamond Fire GL 1000 Pro video card; this sounds a lot like a machine on which the problem had been seen, so I had high hopes for the NTIMECOUNTER fix. However, it doesn't seem to make a difference, even with NTIMECOUNTER set to 2000. For testing I've been doing "sysctl -w kern.timecounter.method=1" in single user mode before going multi-user and starting X. As soon as X comes up the calcru messages start spewing. Is there hope for this machine and video card? Here's the configuration file and dmesg. Thanks, Tim # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # For more information read the handbook part System Administration -> # Configuring the FreeBSD Kernel -> The Configuration File. # The handbook is available in /usr/share/doc/handbook or online as # latest version from the FreeBSD World Wide Web server # <URL:http://www.FreeBSD.ORG/>; # # An exhaustive list of options and more detailed explanations of the # device lines is present in the ./LINT configuration file.
