Looks like 4.19.x is affected (tested 4.19.66) whereas 4.14.x (tested 4.14.138) is not. Also found a way to trigger the bug without the need of a btrfs root partition: btrfs still built into the kernel. Mount another btrfs partition via /etc/fstab at boot, e.g. LABEL="tmp" /var/tmp/portage btrfs compress=lzo,noatime 0 1 Mounting /var/tmp/portage in my case works without problems. But I reliably get the BUG kmalloc-4k at unmounting /var/tmp/portage. I'll try to bisect the next few days and report back. -- You are receiving this mail because: You are on the CC list for the bug.
