that disk.
dmcrypt+btrfs has been working perfectly on OS disk since the beginning.

Title:
dmcrypt+btrfs Out of bounds
Status in linux-signed package in Ubuntu:
New
Bug description:
Getting this IO error when using btrfs + dmcrypt (5 times so far,
reformat between each try) on a DDR5 system w/ built in ECC.
[82228.951950] Buffer I/O error on dev sda1, logical block 35156653829, async
page read
35156653829*512=18000206760448
This value 18000206760448 is between /dev/sda1 partition size and
/dev/mapper/ARCHIVE(btrfs volume) size, but is still slightly out of
bounds of btrfs partition geometry, causing an out of bounds error.
