Hi Brendan, The correct place for Ubuntu bugs is Launchpad, initially. (It might be the case that it turns out to be an upstream/not Ubuntu-specific bug, but we'll go from there.) As Matthias mentioned, recently the patch for the non-512/4k block size (which was an upstream issue, actually) has been released to Ubuntu 18.04 4.15-based kernel. You can check if your stack trace is listed in LP#1867916 [1], for example. And/or test whether the newer kernel version with its fix addresses your issue. If not, please click 'Report a bug' against the 'linux' package in [2]. Hope this helps, [1] https://bugs.launchpad.net/bugs/1867916 [2] https://launchpad.net/ubuntu/ On Tue, Sep 1, 2020 at 5:43 PM Brendan Boerner <bboerner.biz@xxxxxxxxx> wrote: > > Hi, > > I spent the weekend verifying and isolating a kernel panic in bcache > on Ubuntu 18.04 (4.15.0-112-generic #113-Ubuntu SMP Thu Jul 9 23:41:39 > UTC 2020). > > Is this the place to report it?
