[Bug 1784665] Re: bcache: bch_allocator_thread(): hung task timeout
@jason-hobbs, I don't see any kernel error in the log attached to comment #53, so it seems to be a different issue, maybe a performance regression that is causing curtin to timeout. I would keep this bug closed / fixed and open a new one. If you can easily reproduce it, could you open a new bug and collect some info on the box after the problem happens? (in particular uname -a, dmesg, ps axuw).

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
