What do you mean, does this become a crash / kernel panic? Is this a common occurrence and is it due to bad kernel drivers?
- paulmd 3y agoinfamously, geohot encountered and documented a bunch of these kernel panics. https://github.com/RadeonOpenCompute/ROCm/issues/2198 https://github.com/RadeonOpenCompute/ROCm/issues/2198 https://geohot.github.io/blog/jekyll/update/2023/06/07/a-dive-into-amds-drivers.html https://geohot.github.io/blog/jekyll/update/2023/06/07/a-div... they don't occur in amdgpu-pro proprietary userland, but AMD apparently runs that on an internal release cycle and doesn't make the current repo or build available to the public. And AMD just historically hasn't cared enough about the open userland to support that even in the officially-supported configurations. I'll also add to GP by saying that the windows support is all of about 2 weeks old at this point and it's also the first time that consumer cards (as opposed to the CDNA compute cards and the workstation-branded Radeon Pro cards) have had official support. Not that that is a guarantee it'll actually run with AMD though, especially on the open-source userland.
- roenxi 3y agoIt looks like a kernel panic to me, probably bad kernel drivers but I've never tried to figure out what is happening. My graphics card is more than 3 years old (ie, unsupported) so it isn't worth reporting.
