Hello Freebsd-hardware, I've replaced Supermicro X9SCL motherboard with X10SLH. It is C226 chipset. I have "ichwd" device in my kernel config. Watchdog is enabled (default) by jumper. When watchdog is disabled in BIOS driver complains, that it is disable and fails to start. It is expected. When I enable watchdog in BIOS, driver still complains: ichwd0: <Intel Lynx Point watchdog timer> at port 0x1830-0x1837,0x1860-0x187f on isa0 ichwd0: ICH WDT present but disabled in BIOS or hardware device_attach: ichwd0 attach returned 6 But after 5 minutes system reboots! So, watchdog works in this case, but still driver could not attach to it, which makes watchdog useless. Is it known problem? -- Best regards, Lev mailto:lev@serebryakov.spb.ru
