I thought that at one point but that's not true. It's an effective workaround for most (but evidently not all) people with fewer downsides.
On my side, I have updated to my latest BIOS and tried setting the new "Power Supply Idle Control" option to "Typical Current" while removing the rcu_nocbs parameter. So far, so good. zenstates.py reports the following, which makes sense given the option's description.
C6 State - Package - Disabled
C6 State - Core - Enabled
If you don't know what this means, I've read that "core" just powers down the CPU cores while "package" powers down most of the rest of the CPU after the cores. Sounds like an appropriate fix. I'd like to measure the power usage but haven't gotten round to it yet.
