I can confirm that ichwd(4) works fine on the following system types: - Supermicro SuperServer 5015M-T+ (Intel ICH7R-based) - Supermicro SuperServer 5015B-MT (Intel ICH9R-based) - Supermicro X7SBA motherboard (Intel ICH9R-based) - Supermicro X7SBL-LN2 motherboard (Intel ICH9R-based) The Asus P5G41 looks like a workstation-class board[1]. I wouldn't be surprised if certain configuration bits aren't being set by the system BIOS or during the manufacturing process by Asus for this reason. All in all, I really wouldn't worry about ichwd(4) not working for you. If your system randomly locks up, you try to investigate the root cause and solve it. Hardware watchdogs are usually a server-focused feature. Regarding SW_WATCHDOG, it doesn't work on SMP systems, which yours is. So don't bother.
