Attaching the (s)trace of dpkg -i tex-common. As you can see, it explodes right after it opens /var/lib/dpkg/info/texlive-lang-all.list and calls ioctl.

At this point installing other packages results in a similar error. Might be due to the broken upgrade.

The issue appears to be stemming from ext4_fiemap()... Attached trace.

After reboot the issue cleared itself and I could continue the upgrade.

Based on the above it looks like this bug is actually kernel/ext4 related. Changing package assignment.

Do you have a way to reproduce the bug, or was it a one time event?

[dc (darkcharl)]

Not anymore, the bug cleared itself after reboot. Before reboot I could reproduce it arbitrarily.
