Deleting events causes database corruption

I also got the missing prev_events error after purge history API calls. Running Synapse 1.93.0. It seems the problem still exists. I posted a message in [Synapse Admins](https://matrix.to/#/!ehXvUhWNASUkSLvAGP:matrix.org/$881yOVMcHCDz_j9U7bZ4n5zW6NH4GjfJClKCdNjUu9s?via=matrix.org&via=libera.chat&via=matrix.breakpointingbad.com), but I...

[Pi 4B 8GB] When EEE (Energy Efficient Ethernet) is enable and active on eth0 at gigabit speed, ethernet becomes slow to unresponsive with packets dropping

I think #3292 is facing the same issue.

[Pi 4B 8GB] When EEE (Energy Efficient Ethernet) is enable and active on eth0 at gigabit speed, ethernet becomes slow to unresponsive with packets dropping

It seems that the `dtparam=eee=off` hacks only work for Pi 3B+. Disabling EEE via `ethtool --set-eee eth0 eee off` is the proper way in Pi 4 and CM4. This issue...

> My CM4 running Raspberry Pi OS connected to a Netgear GS205 That is very interesting. I happened to test Pi 4 (Raspberry Pi 4 Model B Rev 1.2, 4GB)...

Thank @6by9 and @JamesH65 a lot for the prompt testing results. That is solid proof that the EEE of Pi 4 is working well for other switches. Meanwhile, many thanks...
