Hi,
I was using Debian Bookworm in a Virtualbox VM for quite some time on my Lenovo E585 (Ryzen 5 2500U). On heavy duty in the VM (compiling something, or copying files), applications on the host was buggy (Firefox, Thunderbird, ...) as if the windows host's memory got corrupted by the Debian VM. Sometimes, the screen would go off and some leds of the keyboard would blink link a christmas tree until a pressed the power button long enough to reboot.
I've upgraded the host's graphics drivers, upgraded the BIOS and anything I could basically upgrade but the problem was still there. Last week, I've decided to go dual boot with a Debian Trixie in order to see if things went better.
Unfortunately no, the computer is hard freezing on some pattern that I can reproduce at 100%:
* Opening KiCAD (sometimes I need to open 3 times for the bug to occurs)
* Scrolling down Synaptic Packet Manager (100% rate)
* Printing some python matplotlib things (sometimes it needs 5 prints to freeze)
I've tried some cryptic things like setting the governors to "performance", disabling the power save features of the CPU in the BIOS, Removing one screen, adding "idle=nomwait" in the kernel parameter, etc ... but nothing solves the problem. Nothing shows up in the last log "journalctl -b -1".
Is there any way to debug such thing?
Thanks by advance,
