Fwd: Debian bug#524495: confirmation w83627hf_wdt not rebooting
Hi,
I wanted to provide more details on this closed bug, as I ran into
(I think) the same problem. Could this bug be re-opened?
Best regards,
Jaap Eldering

Subject: confirmation w83627hf_wdt not rebooting
User-Agent: Mutt/1.5.18 (2008-05-17)
Hi,
Not sure I can (or should) reopen this bug, but I can confirm the
reported behaviour that the w83627hf_wdt watchdog module doesn't
reboot my machine when the watchdog deamon is killed.
More details: I'm running Debian Lenny i386 with backports.org kernel
linux-image-2.6.32-bpo.5-686 version 2.6.32-15~bpo50+1.
My system has a Jetway NF76-N1GL-LF motherboard (with VIA VX800
chipset). Loading 'modprobe w83627hf_wdt' gives dmesg output:
[ 25.126132] WDT driver for the Winbond(TM) W83627HF/THF/HG Super I/O chip initialising.
[ 25.126239] w83627hf/thf/hg WDT: Watchdog already running. Resetting timeout to 60 sec
[ 25.127701] w83627hf/thf/hg WDT: initialized. timeout=60 sec (nowayout=0)
As suggested by Romain Dolbeau I've tried loading w83697hf_wdt
instead, both without address and with 0x4E, but it reports:
[ 1229.681655] w83697hf/hg WDT: WDT driver for W83697HF/HG initializing
[ 1229.681743] w83697hf/hg WDT: Looking for watchdog at address 0x4e
[ 1229.681771] w83697hf/hg WDT: watchdog not found at address 0x4e
[ 1229.681843] w83697hf/hg WDT: No W83697HF/HG could be found
[ 1278.900732] w83697hf/hg WDT: WDT driver for W83697HF/HG initializing
[ 1278.900801] w83697hf/hg WDT: Looking for watchdog at address 0x2e
[ 1278.900822] w83697hf/hg WDT: watchdog not found at address 0x2e
[ 1278.900881] w83697hf/hg WDT: No W83697HF/HG could be found
When I use the softdog driver and kill watchdog and wd_keepalive, the
system nicely reboots, while with w83627hf_wdt it doesn't, even with
nowayout=1 set:
[ 279.527568] WDT driver for the Winbond(TM) W83627HF/THF/HG Super I/O chip initialising.
[ 279.527675] w83627hf/thf/hg WDT: Watchdog already running. Resetting timeout to 60 sec
[ 279.529725] w83627hf/thf/hg WDT: initialized. timeout=60 sec (nowayout=1)
$ /etc/init.d/watchdog stop
[ 305.708787] w83627hf/thf/hg WDT: Unexpected close, not stopping watchdog!
$ killall wd_keepalive
[ 353.919846] w83627hf/thf/hg WDT: Unexpected close, not stopping watchdog!
I'd be glad to provide more information, or try to reproduce this
under squeeze, if requested.
Best regards,
Jaap
