> Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
We've had plenty of successful runs on this kernel. I suspect io load or something else may trigger this. We've only seen it once out of tens of not hundreds of runs on Cosmic 4.15.0-29-generic. We don't currently have an easy way to test upstream kernels in the automation runs. If we see this again, I'll poke a bit more on running mkfs.ext4 over bcache devices on Cosmic to see if we can recreate outside of the automation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784665 Title: mkfs.ext4 over /dev/bcache0 hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1784665/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
