systemd spams log with "Failed to dissect: Input/output error" on systems with mmc

here is an updated fix: https://github.com/systemd/systemd/commit/cde942f61bf231ea4a0d50780cdb4e744458daeb#diff-5be2770e81c14245e90d2916ded39491

Status changed to 'Confirmed' because the bug affects multiple users.

Hello all,
apologies if am commenting incorrectly, my first post here
could anyone confirm if the fix mentioned in #1 will be backported to systemd in bionic ?
also any time frame on the completion of the activity ?

Thank you for your time

Hi all,

What is the prognosis for this being fixed in Bionic?

Thanks.

From a quick read of the upstream bug, it seems like this requires commits:
7be1420f44465a96d098a33c12c5a61dcefb14aa
a3a3b6131eb2c44b3b94df973e6edd2e4c8d2095

The first 2 are in Bionic already, so as @marvin24 states in comment 1 only the 3rd should be needed.

Hello Marc, or anyone else affected,

Accepted systemd into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/237-3ubuntu10.32 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

All autopkgtests for the newly accepted systemd (237-3ubuntu10.32) for bionic have finished running.
The following regressions have been reported in tests triggered by the package:

gvfs/1.36.1-0ubuntu1.3.3 (ppc64el)
linux/unknown (ppc64el)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].
