ecryptfs_decrypt_page: Error attempting to read lower page; rc = [-4]

ecryptfs_readpage: Error decrypting page; rc = [-4]

I dont' have this issue showing in dmesg when using 3.19 kernel, only with later kernels. Is it related to selecting encrypted home on install or something?

 I don't notice any issues with performance because of it or have any other error messages. I am using default ubuntu xenial 16.04 with unity.

I think it is possibly caused by steam. I can recreate the issue, cause the lines to show in dmesg. By opening up Steam, load a game, then quit the game, and then quit steam. Then the new error lines will be there. As I said though it doesn't happen on 3.19 kernel.

[cooloutac (cooloutac)]

hmm I can't recreate the issue now. maybe it doesn't have to do with steam.

[cooloutac (cooloutac)]

that cs:go crash was when i tabbed to the desktop I think I was low on ram, probably unrelated. don't know about those libgl errors. I know that is needed for steam. Could it be caused by the nvidia driver?

I had the same issue on linuxmint when upgrading to the 4.4 kernel so I just stuck with the 3.19 kernel there as well where i didn't have the messages. I also tried manually make a cryptswap with password prompt on boot for hibernation but that didnt' help either. I'm gonna test with diff video drivers maybe I dunno.

[penalvch (penalvch)]

cooloutac, thank you for reporting this and helping make Ubuntu better.

In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results.

Thank you for your understanding.

[cooloutac (cooloutac)]

I get missing firmware for noveau. don't know what i'm supposed to do sorry.

[cooloutac (cooloutac)]

after reading those instructions guess i'm supposed to uninstall noveau module? I uninstalled nvidia when it complained about nvidia moduel. I have no idea how to do boot with no modules. would I even be able to boot into a gui? lmao....this is nuts. could I even test steam and the nvidia driver with these kernels? I'm way too noob to be testing this for you it seems, sorry.

I wanted to use ubuntu since it comes with its own apparmor profiles and is officially supported by steam. But I really don't like seeing messages like that in dmesg. I'm gonna go back to arch where they don't use bugged kernels...

Hello.

Today, I've noticed two entries about 'ecryptfs_decrypt_page' and 'ecryptfs_readpage' errors in `/var/log/syslog` file. I have no idea if there was/is more such entries. However, it looks this way:

,----[ ✖ Error ]

| kernel: [25312.360724] ecryptfs_readpage: Error decrypting page; rc = [-4]
`----

There was not any system slowdowns, freezing etc. Anyway, `/home` partition was encrypted during installation with eCryptfs (vide `/home/.ecryptfs/t4/.Private`). Here are some technical informations about system:
