I am wondering how to proceed with this.
Sorry, no idea how to repair btrfs. I would try to check and repair from a rescue system. I suggest you download and raw copy this file to an usb stick:
Then boot it.
I booted into a live session and opened the luks encrypted volume. then
btrfsck --check /dev/mapper/system-root <- Failed with core dump
btrfsck --check --repair /dev/mapper/system-root <- Failed with core dump
After btrfsck showed that it can't run sanely under current conditions, by dumping core, you told it to go ahead and modify (--repair) your disk? Bad move. BTW, 'man btrfsck' brings up the man page btrfs-check(8) which says: "btrfsck is an alias of btrfs check command and is now deprecated." The man page also says: WARNING: Do not use --repair unless you are advised to do so by a developer or an experienced user, and then only after having accepted that no fsck successfully repair all types of filesystem corruption. E.g. some other software or hardware bugs can fatally damage a volume. You may have a hardware problem causing disk corruption. If so, trying to use software to fix your disk would be a mistake, probably. Check your ram by booting memtest86 (memtest86+). If, after sufficient time running the tests, there are no errors, boot your Rescue system and, with /dev/mapper/system-root un-mounted, run 'btrfs check /dev/mapper/system-root'. Do not use the '--force' option.
Do you have a recommended place to report bugs for btrfs?
