Subject: "systemctl suspend" on Linux is not reliable.

How long has it been since last time I used the the emergency sync SysRq?

Today traveled to Surakarta for a family event, I departed from Sragen. I suspended my laptop with "systemctl suspend" and put it into my backpack.

When I arrived in Surakarta, I opened my bag and felt my bag was so hot. It turned out that my laptop was on (not in a sleep state) and everything was spinning at 100% CPU (especially firefox and vscode).

I had a chance to check htop and tried to kill firefox with "pkill -9 firefox", but then the system froze.

When the GUI froze, I could still see my caps lock button was still working indicated by the caps lock LED on-off still responed to my input.

I tried to jump to tty4 and tried to login, but then soft lockup warnings appeared, everything froze. I could not login from tty4 neither.

I invoked an emergency sync procedure (Alt+SysRq+s) and forced my laptop off. Unfortunately, the SysRq to print backtrace was disabled. I am not sure how to debug this.

I hope this was not a kernel bug, just hope it was a random bit flip in my RAM caused by an extrme temperature that led to this scary incident.

Hopefully, my persistent filesystem will still be ok, not corrupted.

It appears that the #Intel #I219V e1000e driver for #Linux now supports #IEEE #1588 #PTPv2 precision timing with hardware #timestamping on the #ThinkPad P14S. I'm still qualifying it against an #I226V based master clock on my #LAN across an #FS #S3900 (non-retiming, no boundary clock) in P2P mode. The master is hosted on #Proxmox 9.1, and has a PCIe serial card ready for a GPSDO. There is also a #SiRFStar IV based USB GPS for it to fix to #utc but sadly it doesn't emit# PPS pulses on DCD.

#Trieste 🇮🇹 Centrale last Friday. Pictured here is the #FS #Trenitalia #InterCityNotte #770 for Rome, which didn’t run because of a strike. Hauled by two Class E402B electrics, top’n’tail, the consist included seat cars, couchettes and a T3 sleeper (one of just a few, it’s got some “Excelsior” cabins with en-suite facilities).

On the last train for today: a 250 kph #FS 🇮🇹 #Trenitalia #Frecciarossa Class #ETR600 high-speed tilting train takes me from #Milan to #Venice. It’s got a sort of #DiningCar, labelled “Freccia Bistrò”. Well, it’s a counter where one can purchase drinks and light meals from a
lovely steward, and take them to one’s seat.

#FS 🇮🇹 #Trenitalia #InterCity trains, like the #Ventimiglia to #Milano one today, haven’t got a proper #DiningCar in their consists. Yet, in most cases, there’s a multi-purpose car with vending machines and an area with bar stools. The espresso coffee, it costs 1.30 Euros, is actually quite decent.☕️👌

With #Trenitalia 🇮🇹 #FS #InterCity from #Ventimiglia to #Genova and #Milano. Beautiful scenery, as we pass along the #Mediterranean and through coastal towns.
