The bus errors could be from a few things, but as they're corrected errors, I did what any sane person would do, I turned PCIe AER (Advanced Error Reporting) off with pcie_aer_disable=1 ;)
A throw back to my post on running a Win11 ARM64 VM on the pi5 (https://imgur.com/gallery/KRZlO2W), I ran some CrystalDiskMark benches inside the Windows ARM64 vm.
The first 2 are with PCIe AER on, the next 2 off. You can see some boost in random access, that's prob the cpu cycles I got back from not spamming my system log.
Of course turning off reporting doesn't fix the errors, but for now, it meets my needs

Is it still plague with that USB issue from rpi4?

Thanks for posting this. I picked up a Pi5, saw the PCIe thing on the back and am wondering when someone will sell an adapter for full size cards. That could be very useful as I'd like to get a RAID controller and run a pair of SSD disks for reliability at high speeds.

I already have a m.2 to x4 slot adapter. I plan to test a 10g nic and sas controller. Adapter https://www.amazon.com/dp/B09N1FYCQZ

Oh that is interesting. I have a nice model 1 Turing Pi I use as my mini cluster and am now going to try the CM3-4 blades. Should be interesting with a 5 pi SAN.
