Do you have the log for this operation?

When I attempt to perform the quick-wipe on disks that have been configured
in bcache mode
that operation fails. I'm interested in if you're also seeing this.

There is no change in config (which is good).

Do you have the entire log here? In the early part of the curtin install
process, curtin dumps
the block device tree layout w.r.t which devices has a holder (like
bcache). I'd like to see what curtin
saw on this second run.
