Date: Mon, 29 Jul 2002 10:38:31 -0400 From: "David E. Cross" Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I haven't seen microuptime messages in a _very_ long time; over this weekend I replaced the PowerSupply a couple of fans and the CPU heatsinks in my computer (none were yet "bad", but one of the CPU fans was starting to slow down, and I had a problem warm-rebooting the machine: it had a 90% chance of hanging from a warm reboot, even if I hit the reset switch before the BIOS even passed control to boot/loader). After these upgrades I started receiving lots of microuptime errors (note that the reboot problem went away). Has anyone seen them? Do they know what they are indicative of? (Is it time to toss this MoBo?) Below is my kernel config dmesg, dmesg of errors, kernel config. The brief version is: dual Pentium II-400Mhz (ecc Cache), P2B-DS ACPI 1012 BIOS, 512M ECC. Microuptime errors are usually small (1/1000ths of a second, but some are VERY large; 4 or 5 seconds), timecounter is PIIX, method 0. I included so many of the microuptime errors because it apparently gets "stuck" at certain points for long periods of time. -- Boot Dmesg -- Copyright (c) 1992-2002 The FreeBSD Project.
