Hawkins" Date: Mon, 14 Jan 2002 15:14:03 -0500 Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I have been having hardware freezes since ibm swapped the motherboard on my A21p. These freezes happen both under freebsd and win98. Before freezing, the cd drive is spun (but disabling it in the bios and/ or kernel does not stop the freezes). Heat seems to be a factor; it happens more on warmer days and at my house (where it's likely to be on my lap). It's not a bad dimm; I've swapped slots andrun with both singly, and the problem remains. I can also compile with loads near 10 without triggering the problem (on the right days :). I've found now thatI can duplicate the problem on demand. Writing to the dos partition usually triggers a panic. I can halt and reboot, but "init 1" seems to cause it every time. Sometimes I get a readout, while other times I am informed of the panic. It claims to sync the disks, but they're still dirty on reoot. The offending process seems always to be ngctl I knowI have a serious hardware problem, but I'd like to be able to point to something specific that they can find (rather than trying to blame the OS). The message is roughly (hand copied, then typed): (values in parentheses are from additional runs).
