Eventually something happens to it though, and then it is not right again until reboot. The behavior then is an occasional freeze, where nothing moves for 10 seconds or so, then full-speed network I/O for a few seconds, then another freeze, etc. I only got this machine recently. I first installed Debian Sarge on it, and had the same problem with Sarge's 2.6.8 kernel. I read many messages about the NETDEV WATCHDOG situation, and some writers suggested it might be fixed in later kernels, so I upgraded to Etch with the 2.6.18 kernel. For me at least, the problem is still the same. I am holding the machine in the broken condition (rather than rebooting) in case anyone wants me to test something else. Here is some info to document the problem: dmesg at boot: Linux version 2.6.18-4-686 (Debian 2.6.18.dfsg.1-12) (waldi@debian.org) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) #1 SMP Mon Mar 26 17:17:36 UTC 2007 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009f800 (usable) BIOS-e820: 000000000009f800 - 00000000000a0000 (reserved) BIOS-e820: 00000000000e7000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 00000000040fd800 (usable) BIOS-e820: 00000000040fd800 - 00000000040ff800 (ACPI data) BIOS-e820: 00000000040ff800 - 00000000040ffc00 (ACPI NVS) BIOS-e820: 00000000040ffc00 - 0000000018000000 (usable) BIOS-e820: 00000000fffe7000 - 0000000100000000 (reserved) 0MB HIGHMEM available. 384MB LOWMEM available.
