All,
I previously had issues with hibernation when using bcache. It seems
that these issues were coincidental. I am using Debian Wheezy and
hibernation worked correctly with the 3.10 stock kernel; when I moved to
3.11 kernels I had built myself, hibernation stopped working. It would
seem that, for reasons I do not currently know, it was necessary for me
to create a file /etc/initramfs-tools/conf.d/resume containing a line
"RESUME=UUID=..." (with the UUID of my swap device) and then run
update-initramfs. This is Debian Wheezy; depending on distribution,
YMMV. Normally, the .../conf.d/resume file is supposed to be
autogenerated or the swap is supposed to be detected at startup. I'm not
sure why this stopped working for me. In any case, bcache doesn't seem
to be causing me any hibernation problems on Linux 3.11.5 and I'm
thrilled. :)
Cheers,
Zach
