ICH WatchDog driver can not attach on C226 chipset even if watchdog is enabled in BIOS and works

[Lev Serebryakov]

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?
