   is it normal for vddgfx of amdgpu to fluctuate and drop to 731mV?

     trying to figure out why, once again, my work pc (intel i9-9900) has freezing issues again (display stays on, sound stops, needs power cycle). before the freezing i get audio dropouts and cursor stuttering

     @manawyrm ok, thanks for confirming... then the issue is elsewhere

     @mntmn mine only goes down to about 800mV, but it's an older RX580... but sure -- that's very normal.

     nothing in dmesg, core temps are normal, (around 30 degrees), hyperthreading is already turned off since a few months

     @manawyrm it just froze again but memory was normal, like 2-3GB use of 16GB. it feels more like it's PCIe/GPU related. will go through your items above, thanks

     @mntmn audio dropouts / cursor stuttering could also be a memory leak. Connect from another machine, have htop open and look at the memory usage. Out of memory condition (especially in the kernel, due to a leak) can cause hangs like this.

     @mntmn things I'd try (in this order):
     - connect hardware RS232 and configure a console, so you can see kernel output at freeze
     - update kernel to master
     - update BIOS
     - update vBIOS
     - reduce PCIe Gen on the GPU
     - reduce memory timings to JEDEC defaults (no XMP)
     - disable (lowest) C-states
     - disable PCIe ASPM
     - if running with 4 DIMMs, reduce to 2 DIMMs

     @gsuberland where would i find these logs?

     @mntmn I ask because I've had three hardware issues that matched these symptoms, and each time the MCA/MCE logs generated by hardware were critical to tracking down the source.

     first one was caused by PCIe ASPM; worked around by disabling ASPM, and fixed in a later BIOS.

     second one was a bad DIMM with a very transient fault. ECC correction events told me which DIMM.

     third case showed internal cache faults on one of the CPUs; the cause was motherboard failure.

     @mntmn any MCA/MCE logs being generated?

     @mntmn I had similar problem that was fixed by disabling cstates in the bios. That was on amd hardware, though.

     @rev_null ok, i disabled all power mgmt as well now

     @manawyrm ok so BIOS was really outdated (2018), i updated that and disabled power mgmt features in BIOS incl ASPM. appears stable now, lets see

     @mntmn tbh I would really love to see some such cyber firmware setup menu in the open source space
     I have ideas that I presented at FOSDEM a few years ago, "firmware settings and menus"
     and we are discussing runtime setup tools in the coreboot community
     WDYT, would that be interesting for the Reform laptops?

     @mntmn looking at the bios revisions and fixes, this has a good chance of improving your desktop stability 🤞
