3.16 kernels broken on i686 up until rc2 (affects installed systems and nightly images)

Posted by adamwill on June 23, 2014

There was a significant bug in all 3.16 kernels affecting the i686 architecture (32-bit Intel) only. This resulted in all sorts of breakage higher up the stack – dbus would not run, for a start, which causes many other problems. Installed systems might just limp to a console login; of nightly images, both lives and boot.iso images failed to boot fully.

The cause of this was recently identified and a fix submitted upstream. The fix has been pulled into Rawhide immediately, starting with kernel-3.16.0-0.rc2.git0.1.fc21. All 3.16 kernels prior to that should not be used on i686 machines, or you should pass the kernel parameter vdso=0 to work around the bug.

Nightly images should start working again (or, at least, not be broken by this particular bug…) starting from tomorrow, as the fixed kernel is pulled in.

  1. Thanks, my i686 recently was broken with lots of errors with kernel 3.16.
