so the DMA bug I have been chasing for the past almost-year on my thinkpad?

@ariadne if I may paraphrase an old joke...

software contractor is called in on a job
spends six weeks going through the repo, tracing the test suite, etc etc
sends one character PR and faxes an invoice for $100,000
client says "wtf! itemize that please"
- $1 per character changed
- $99,999 for knowing which one to change

hmm, that's not it.

[ariadne@social.treehouse.systems]

i think i might just have more general EL2 instability issues that i am chasing now

[ariadne@social.treehouse.systems]

sure would be nice for lenovo to incorporate newer gunyah package from qualcomm into their firmware though 🙃

[ariadne@social.treehouse.systems]

i wonder if this is the SoC watchdog freaking out and rebooting the machine sometimes

[ariadne@social.treehouse.systems]

i hacked in the definition of the SoC watchdog from another patch in the linux 7.0 patchqueue and it hasn't blown up on me, so i am guessing that is the missing piece

[ariadne@social.treehouse.systems]

it seems that qcom-wdt is now properly keeping the watchdog maintained, so hopefully that is the end of my woes and i can just enjoy a stable machine with EL2 and 64GB RAM

also maybe it would be nice if lenovo just updated gunyah (there has been a fix for like 9 months now from qualcomm) in the next firmware update. but as far as they are concerned this is a windows on arm laptop and they do not care about linux, it seems.

[ariadne@social.treehouse.systems]

next time i will go with dell

[ryan@m29.us]

@ariadne Not the same class of issues, but coincidentally this weekend I bought a Dell (amd64) mini-desktop to replace a failing no-name Mac Mini form factor clone as my edge router. It was the cheapest option for my needs given [AI ruins everything]. Motherboard of course is proprietary but I was impressed with the UEFI setup program. And it fits in a Kallax cube.

[ariadne@social.treehouse.systems]

this really is otherwise a quite nice machine. it just sucks being an early adopter of qualcomm snapdragon elite, because the older snapdragon 8cx was less buggy...
