Sproul" To: Subject: mysterious lock-ups Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hardware@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi, I am experiencing mysterious lock-ups on a brand new 4.2 box that I recently built. I have very little evidence to go on since *nothing* is logged-- making me think it's hardware-related. The system becomes completely unresponsive from the network as well as the serial console. All I have that is somewhat unusual are some console messages related to the net card. This system has an FIC AZ-11 board with an AMD Duron 700 and 128 MB of Kingmax "TinyBGA" SDRAM. I am not overclocking the chip. The hard drive is a Western Digital WD205BA (20.5 GB 7200 RPM ATA-66). The network card is a Linksys LNE100TX 10/100 PCI. I have built a custom kernel with the following netcard support: device miibus # MII bus support device dc # DEC/Intel 21143 and various workalikes It shows up in dmesg as: The console messages that I saw were: Feb 16 09:13:59 gryphon /kernel: dc0: TX underrun -- increasing TX threshold Feb 16 09:14:11 gryphon /kernel: dc0: watchdog timeout Feb 16 09:56:20 gryphon /kernel: dc0: TX underrun -- increasing TX threshold I have never seen these before so I don't know if they are unusual or just normal. Could this be related to a lock-up or do I need to check elsewhere?
