Actually, had this only occurred this week, I might have put my money on it being caused by the “biggest ‘solar radiation storm’ in 23 years”. But, alas, I did have that one incident on the 11th.
Cool, I’m not going crazy! I’ve had a very, very similar issue for a couple of weeks now. Identical in fact, except for the triggers and frequency: three incidents so far, since the first one on January 11th, with the last two within two days earlier this week. In all instances I’ve had Twitch playing video in Librewolf, when suddenly the desktop freezes, leaving only a 500 ms bit of the audio looping endlessly. I had forgotten about magic SysRq, so I have yet to try if it works; I’ve also just done a hard reset instead.
If the logs posted by anonymousdormouse are related to the issue, then that’s one difference wrt. what’s happening here: there’s been nothing related to the problem in any logs. The system seems to just die instantly and completely.
Ubuntu is on an NVMe drive instead of a HDD, and it’s the only OS on the drive.
I have done one pass of memtest to rule out memory errors.
My system doesn’t have Nvidia, it’s using the integrated GPU of a Core i7-8700 with two external displays (one DP-connected, one HDMI-). (This is a Dell XPS desktop that originally came with an external Nvidia GPU, but I ripped it right out before installing the system. I’ve had enough bad experiences with Nvidia to know to avoid them whenever possible.)
Kun avaan tämänpäiväisen sisäpyöräilysuoritteeni muokattavaksi Connectin web-näkymässä (Vivaldilla tai Firefoxilla), ja yritän syöttää matkan pituuden, joka on 33,24 km, sivusto vaihtaa itsekseen pilkun tilalle pisteen, ja sen jälkeen valittaa, että tämä ei ole kelvollinen lukema: ”Your 33.24 value is not within permissible limits.”
Samaa virhettä se valittaa tietysti myös, jos syötän alunalkujaankin pilkun sijasta pisteen.
Jos typistän lukeman 33,2:een, se menee läpi.
Jos muokkaan samaa suoritetta puhelinsovelluksessa, se tallentaa kaksidesimaalisen arvon ihan mukisematta.
Aiemmin nämä ovat kelvanneet webissäkin ihan hyvin.
Cool, thanks for the quick fix!
I’ve been using a custom template, which I’ve hooked in via the vlp_get_template filter in my theme, to format previews in the blog’s RSS feed to my liking.
With 2.2.8 this seems to be outright prevented:
“Fix: Only output link in RSS feed”
Indeed, there’s now a branching upon is_feed() in VLP_Link::output() before VLP_Template_Manager::get_template() is called, so my filter is never applied.
Would it be possible to have a filter for the feed case too? I see there’s been someone with a problem with their RSS feeds, but having just the link in the feed is a bit too simplistic for my use.
This happened again, and the only common factor with the one above was Totem playing a video again (this time I wasn’t messing with the timeline, just watching).
Lieköhän unohtunut tuo kaatunut varoitusmerkki tuohon työn jäljiltä? Koulun ja Ranta-Toppilan välinen pätkä uusittiin kesällä, eikä muita töitä nähdäkseni tässä kohtaa ole tekeillä.

I was editing a video in Kdenlive (in that I had the project open on my first monitor), and was simultaneously scrubbing one of the input clips on my second monitor using Totem, when the crash occurred.
Not much further info at the moment that I can think of. Just making this initial report so that I have something to refer to, should a similar crash occur again.
4.7.1 was released three weeks ago, but as I’m writing this, prebuilt binaries have yet to appear on the release page. Maybe the build jobs have failed?
I’m still getting federated posts from updating old ones on my blog (with the plugin now at version 7.5.0). Not every time, but something like four out of maybe two dozen that I edited today (from 2018) have so far appeared on Mastodon.
Should I open a new report? I noticed the merged PR (above) mentions the block editor, whereas I’m using the classic editor.
