Title:
bcache: overflow in stripe number calculations for devices with small
io_opt
Status in MAAS:
Fix Released
Status in linux package in Ubuntu:
Fix Committed
Bug description:
Ubuntu Focal
ga kernel
This problem was originally reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=1783075
Using the linux-generic-hwe-20.04-edge packages resolves the issue.
We hit this while exploring storage options for PS5 where we would
like to put a Optane as cache device in front of a NVMe SSD backing
device with 512 byte optimum I/O size.
While the problem appears to be fixed for the kernel we file this bug
to document a need for Focal hwe-edge images for commissioning/deploy
in MAAS.
