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.#linux #sysrq #sync #fs

The watchdog reported CPU#6 stuck for 5946s (observed from the photo).That is roughly 99 minutes bake, lol.That means my laptop didn't just wake up right before I checked it.It likely woke up and hit soft lockups almost immediately after I put it in my backpack and was running at full tilt for the entire journey from Sragen to Surakarta 😭Shit.

Dumping read-only files to a cold storage mounted with "compress-force=zstd:15" btrfs option :ablobcat_no_dakko: Curious, how much space I can save with that level of compression. The files are mostly git blobs, SQLite DB, and text files. I think they should be very compressible.

@cell It's true for me, but it may not be for others.Reading emails and reviewing code on weekends is not a problem for me. I love the activities apart from my job.Actually, I have sent hundreds (or maybe thousands) of patches without getting paid, and I love doing that.BTW, I can sit at my computer for more than 14 hours a day (only given short breaks).[ Not sure if I will still feel that way as I get older. ]

@cell I also have two computers next to my bed. They are on 24 hours non stop. When I wake up in the morning, the first thing I do is check my computers (and my phone). It feels like they have become a part of my soul. Lol.I am glad the computers I have in my bedroom don't make too much noise (unlike servers or gaming rigs). They are pretty quiet, so they don't disturb my sleep.

@cell My big machines are accessed remotely, so their noise doesn't bother me.

I just unpacked an old Asus router from my suitecase.I brought it to Jakarta from Sragen during the Eid Fitri holiday. But did not have enough mood to get it run until today. It stayed in my suitecase for 2 weeks.I plan to use it for testing my apps, making sure my apps can run on the MIPS architecture.

Sadly it is an LE machine. I wish I got a BE machine because my testing should also prove that I correctly handle endianess diversity across various architectures.

@cell I have several servers like that, too. This one has the longest uptime.
