Weird errors accessing the disk under kernel 4.3.3 (PAE)
Last modified: 2016-01-29 08:11:12 EST
Description of problem:
After updating to version 4.3.3-300 (PAE) weird errors like:
ata2.00: exception Emase 0x0 Sact ...
started appearing, with occasional corruption of files in the filesystem
Version-Release number of selected component (if applicable):
The errors above appear in /var/log/messages soon after boot
This problem was addressed and fixed upstream:
and seems specific to the PAE kernel, so probably it is enough to just update to the new kernel version.
Thanks for the pointer to the patch. I've added it in Fedora git since upstream stable seems to be really behind.
I see that kernel-PAE-core-4.3.3-301.fc23.i686.rpm is in updates-testing. Should I try it? My current situation is that I must boot with an older kernel, otherwise (with 4.3.3-300) I am losing data!
No, that kernel does not contain the patch for this bug. It will be in the next build and the updates system will leave a comment in this bug when it is present.
kernel-4.3.3-302.fc23 has been submitted as an update to Fedora 23. https://bodhi.fedoraproject.org/updates/FEDORA-2016-db9fedd7c4

I would like to urge the move of the kernel update from updates-testing to
The motivation is that most users of PAE kernel, version 4.3.3-300 (there might still be a fair amount of them) will probably experience strange errors even with occasional data corruption on their ATA drive without even knowing that the responsible is the kernel... The only way to fix their problem would be through a regular update!
It's being submitted today.
I am puzzled... The package disappeared from updates-testing, but it is still not
present in updates. Is this ok?

Yes. It's in the middle of being pushed to stable and the kernel that replaced it (4.3.4-300) also contains the fix. Everything is fine.
kernel-4.3.3-303.fc23 has been pushed to the Fedora 23 stable repository. If problems still persist, please make note of it in this bug report.
