This sounds like a BIOS problem to me.

If it works properly with another kernel version, then it's mostly likely a kernel issue, but if it's consistently slow across kernel versions, then a HW/BIOS problem seems most likely. The first version to try would be the one from Stable-backports, which according to https://tracker.debian.org/pkg/linux is 5.16.12-1~bpo11+1 Next would be the kernel version from Testing, but (even) better would be the one from Unstable (which is now 5.18.2-1, but that version may not be available everywhere just yet as it was uploaded yesterday). https://snapshot.debian.org/ is a way to retrieve other/older versions of Debian packages, so that may be of help. It is also useful to test older versions of the 5.10 series to see whether there has been a regression since. At https://snapshot.debian.org/package/linux/ you can find older kernel versions. F.e. 5.10.46-4 or 5.10.84-1 sound like useful versions to test. So if you could test those other kernel versions and report back the result, that should help.
