Does it work as far as device attachment goes? The verbose dmesg is as follows. Thank you for the investigation and the patch. Instructions from Linux itself: Show Obsolete 1 View All Add an attachment proposed patch, testcase, etc.

Comment 1 Konstantin Belousov Also, you would need to invent a unique rid for the new resource and consistently use it in both set and alloc. Anyway, I’ve got the following verbose message with my patch applied. Comment 4 Andriy Gapon The Linux test detail watchdof described in the following page.

Thank you for the investigation and the patch. Or is this already in?

Hardware watchdog

I am greatly interested in knowing which motherboards work and which don’t. We generally assume that the computer boots following the UEFI protocol although indications will be given on how to perform the test with a traditional BIOS. A hardware watchdog is a feature included on many computers, whose purpose is to reboot the computer automatically in case the system hangs: This should open a terminal as shown next:.


Please report tcp motherboard manufacturer and model, your BIOS vendor and version if knownwhether booting through UEFIand whether using a graphics card or CPU -integrated graphics chipset and what other extension cards may be present.

No hard disk drives are required. Since all our alerts came through Slack rather than via email and I didn’t want to have to set up sendmailI wrote a quick python program that would accept input in yco same format as sendmail but send off a POST request to a slack webhook instead. Maybe fixed resource allocation. This may be a BIOS or even a hardware issue.

I am particularly interested in test cases where at least one of the following conditions holds, and even watchdot so if several do: If all three appear, the watchdog was correctly detected. Description Greg V The Linux test worked correctly successfully rebooted on this ThinkPad, though my patched ichwd didn’t.

Now type sudo su to watchdig administrator and the prompt should change to root ubuntu: Comment 24 Andriy Gapon If booting through UEFIthe screen should appear as shown on right. Please report this as a failure. The prompt will not return do not press control – c nor control – dsimply wait.


This will cause the watchdog to start counting down. Mon Oct 22 I used the heartbeat-file to monitor the heartbeat with Telegraf:. Comment 14 Dries Michiels The point is to detect those motherboards whose faulty hardware or buggy BIOS make the watchdog dysfunctional.

– [ichwd] New Intel TCO Watchdog Timer (Skylake/Sunrise Point and newer) is not supported

My test system did not have either of those problem, so, again, I decided to leave those cases until later. If you are interested, this is what Linux does for that bit: Look for lines such as the following preceded by numerical timestamps:.

It’s designed to handle unrecoverable errors, like when the operating system freezes. I did not received the advise about co-existence of drivers. On the other hand, with or without my new patch, ThinkPad now reboots successfully upon watchdog timeout.
