I bought a new graphics card yesterday, and it came with a freebie. now my machine hangs whenever I boot a kernel with lockdep enabled.

Here is the link to the issue I posted on GitLab: https://gitlab.freedesktop.org/drm/nouveau/-/issues/237

BTW does DRM folks prefer using GitLab or the mailing list?

I want NVIDIA's proprietary GPU drivers 🥲
nouveau does not support virtual GPUs...

I was refreshing my zsdesc patch series but encountered unrelated bug while testing (I bought new RAM so it must be software bug...)

Fortunately it was bisectable and I'm writing a report about it
Not sure if people will welcome an oops image instead of text format.

a funny thing about memtest is that it can fail due to memory failure.

@ljs hmm I tried to boot using two different bootable USBs but both says something has been corrupted. It makes me think the kernel may be innocent

@ljs directly on host, it was wild memory access according to KASAN.

@ljs sometimes during kernel compilation, sometimes while shutting down the machine for rebooting...

today I was hit by a kernel bug on the latest mm-unstable and so I was debugging it. but after a few kernel crashes even a normal kernel doesn't boot.... what's wrong with you :(

Not sure if it is a filesystem corruption caused by kernel bug, or they just did happen independently.

I have the last final exam today. haven't decided what to do during the summer vacation yet, but it will mostly involve learning new things and writing some kernel code.

It was 2004 when I got my first computer, but I don't recall the precise model. it was shipped with Windows XP.

The first time I used Linux was Android on my Galaxy S3 phone in 2013; after that, I started using Linux on my desktop since 2014.
