@ everyone running #Linux 5.1 and a device mapper filesystem (dm-crypt/LUKS, LVM) on a SSD: There's a data loss bug! bugs.archlinux.org/task/62693
Just did an emergency downgrade after hearing about it in #binaergewitter.
Luckily `btrfs scrub` doesn't report any errors, so hopefully no data loss for me.


@schmittlauch Woah. I know it's bad to say this, but good thing I didn't do full disk encryption with this Arch install.

Does this apply to external devices as well?

@masterofthetiger Yes, everything using device mapper and using the SSD trim command (so no spinning disks).
But the fixed kernel 5.1.5 should already be available in Archlinux

@schmittlauch Oh whew. I was starting to worry. I use encrypted external hard drives and flash drives all the time. I see that I already have 5.1.7 installed.

As far as you know, what issues could this have caused?
