Indeed, I also have the internal drive encrypted with LUKS, also jfs
on it, but the problem only occurs on the external drive.

Is there the possibility that the JFS on the external drive got into a
state that may caus JFS to behave unexpected? If this is true, it would
explain why it happens only with the external drive and also accross
kernel versions.

But "good" to hear I am not the only one affected anymore.

Cheers,

Nico
