On my chromebook samsung peach pi (exynos-5800) wifi driver stops to
work at random time, sometimes after few hours and sometimes after day
or two.

I don't have official recommendations, nor HW to test at the moment,
but for the record, Peach Pi should have Marvell SD 8797. You can see
what firmware Chrome OS used to ship for those devices here:

https://chromium.googlesource.com/chromiumos/third_party/marvell/+/HEAD/sd8797_uapsta.bin
https://chromium.googlesource.com/chromiumos/third_party/marvell/+log/HEAD/sd8797_uapsta.bin

On these urls I can't find actual file to download, or I'm blind (or
don't understand how this site 'works').
Whatever I click I get new url and not binary file to download.

Could you give url for binary file that I could download, please?

Notably, the versioning there (e.g., W14-66-27-p18) suggests it's a
different branch (?) than what's currently provided in the main
linux-firmware (W14.68.29.p59). So you might give a try at replacing
the file in /lib/firmware/mrvl/. No guarantees though.

kernel is mainline 5.14.4 without patches, but I recall that I noticed
this crashes on older ones but can't remember exact version.

Did it ever work well? I'm curious if this was a kernel regression, or
perhaps just a long-standing firmware issue.

Yes, it worked for few years but started to crash about few months ago
and that happened when I upgraded complete root filesystem, so it could
be related to upgraded firmware. Thank you for hint what to try to test.
