Hi Sebastian and Ryan, I've created the setup that each of you described on a VM, but unfortunately it wasn't able to reproduce the problem.
I double checked the output of lsblk with Sebastian's and it's the same (also the bcache sysfs configuration/status), and with Ryan's description, and both matched. So apparently there's something else involved into bcache, maybe a timing or corner case specific to actual hardware. Ryan, since you're able to help w/ additional info/testing (thanks you!), could you please collect a kernel crashdump? I'll provide the configuration/test steps in another comment. Should you have any questions or need assistance with those, please just let me know. cheers, Mauricio -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867916 Title: Regression in kernel 4.15.0-91 causes kernel panic with Bcache To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1867916/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
