500 error on block/blk-core.c in the kernel

[skitt]

See https://elixir.bootlin.com/linux/v6.10.9/source/block/blk-core.c:

This happens on all versions of the kernel I’ve tried, back to https://elixir.bootlin.com/linux/v2.6.39.4/source/block/blk-core.c at least.

Hello,

I can't reproduce this. Does this happen when you click on an identifier? Or on a source page?

[skitt]

Wow, it’s working now... Presumably a transient issue then. It happened whenever I tried accessing blk-core.c in any way, including through the links in the initial post.

The logs have traces:

This is somewhat known; but we have (1) no tracking issue and (2) no fix currently. I haven't digged deeper but it is surprising that it can resolve itself over time. IE we seem to get an error from data read from database, but it stops appearing over time.
