never thought it was...

but there's a difference between experiencing issues (unlikely to be
related to myth) and strongly recommending people not upgrade.

You've stepped into the bandwagon whenever someone ask about 0.26 and
not upgrading.

This is non-constructive and unhelpful, and actually prevent work to
properly progress.... We're up to 0.27 now, even if there *may* be
issues, that people stick to 0.25 doesn't allow to fix 0.26. Only with
mass adoption can you acquire the critical mass required to fully
cover the application

read above...

and there's been no changes between 0.25 and 0.26 in that part of the
code. Only changes that occurred in the past 2 years in that code is
related to the UTC changes.

and you're not using ext4 and enabled barriers by any chance (barriers
used to be turned off by default in earlier version of the linux
kernel, and now are on)
that alone would explain many of your issues. Which would have
happened with 0.25 (or any earlier version of myth for that matter)

You're not running 0.27, so how could you confirm one way or another ?
