Bug in EHCI/USB stack?
Posted: Sat Jan 14, 2023 2:54 pm
I always had problems with cold reboot (especially the CTRL+LALT+RALT option) getting stuck since the day i got my x1000 hardware.
Lately i was able to catch some pretty strange output, see here
This shows up frequently (but not always) AFTER the CTRL+LALT+RALT key combo and kills the reboot process permanently (case button needed to reboot).
Not sure if it's a (USB) hardware problem with one of the attached devices (though i only have a perixx mouse/keyboard combo and a midi to usb converter plugged in, since years) or a usb stack/EHCI bug.
Anyway, when this error doesn't come up chances are high the key combo for cold reboot works fine (but still not 100%)...
