I installed reiser4 -enhanced Linux kernel 4.17.19-1 --thus replacing the prior hung reiser4 -patched kernel 4.18.15-1 in the Google Compute Engine (GCE) cloud instance. After less than 24 hours the 4.17.19-1 hung in similar way to the 4.18.15-1. Please note that I had been running my custom Metztli Reiser4 Debian Stretch image with reiser4 linux 4.14.20-1 without issues for several months < https://github.com/Metztli/reiser4-debian-kernel-packaging-4.14.20 > --until I decided to upgrade to newer kernel(s). Below is the relevant section for 4.17.19-1 --remotely obtained by serial output: [91343.247237] INFO: task kworker/u2:1:2363 blocked for more than 120 seconds.
