BTRFS error count 754 after reboot on Debian kernel 6.12.17

I have a test system which has a strange problem where the BTRFS error count 
on one device (out of four) goes to 754 after a reboot.

There are no BTRFS errors in the kernel message log after booting up.  There 
are no log entries in /var/log/kern.log about BTRFS issues.  When I look at 
the console as it's shutting down I don't see any errors being logged, so 
either there are no errors logged or there are 753 errors logged in the final 
split second before power off or reboot so that I don't even see them.

This is repeatable and it's 754 every time.

After I get the error I remove the device from the array and add it again.  I 
can run it for days without problem with data being written to that device and 
read from it without error.

But when I reboot it says 754 errors.  When I swapped that device with another 
one in a different drive bay the same device has errors and the other device 
doesn't.  So it's not related to the drive bay it's related to the SSD.

The system is a Dell PowerEdge T630.

The SSD could have a fault, but if so why does it only show up on reboot and 
why 754 errors every time?
