Description Peter Robinson 2017-03-26 22:42:45 UTC
In recent time we started putting the bcm2835-dma in the initrd because it offered a substancial bump in performance but it seems this has caused as many issues as the performance bump it provides including non booting devices.

This should be dropped until the problems are worked out.

It affects both the Raspberry Pi 2 and 3 in a number of situations that aren't fully known yet.

Comment 1 Peter Robinson 2017-03-27 07:45:45 UTC
This has been submitted as an update, seems bodhi hasn't updated the bug

Comment 2 Fedora Blocker Bugs Application 2017-03-27 07:47:15 UTC
Proposed as a Blocker for 26-alpha by Fedora user pbrobinson using the blocker tracking app because:

 Raspberry Pi is a key ARMv7 platform device. Fix is in place so shouldn't slip, doesn't impact other ARM devices or the rest of the distro

Peter, could you identify which criterion on https://fedoraproject.org/wiki/Fedora_26_Alpha_Release_Criteria you feel this is violating? Otherwise, this sounds more like a Freeze Exception request.

Comment 4 Paul Whalen 2017-03-27 14:30:42 UTC
Some users are reporting a kernel oops on the Raspberry Pi 3, a supported hardware platform. Citing criteria "Release-blocking ARM disk images must boot to the initial-setup utility."

Comment 5 Stephen Gallagher 2017-03-27 14:46:20 UTC
It seems pretty harmless; I'm in favor of granting it at LEAST an FE and getting it into the compose that's about to kick off.

That should have read: "The fix seems pretty harmless"

Comment 7 Mike Ruckman 2017-03-27 14:49:02 UTC
+1 FE since the change won't impact other things.

Comment 8 Nick Bebout 2017-03-27 14:50:58 UTC
+1 FE

Comment 9 Paul Whalen 2017-03-27 14:52:33 UTC
+1 FE/blocker , change is self contained

Comment 10 Adam Williamson 2017-03-27 15:41:49 UTC
+1 blocker for me, if Pi 3 is a supported ARM platform and this breaks boot on it, seems pretty straightforward.

Comment 11 Geoffrey Marr 2017-03-27 17:10:17 UTC
Discussed during the 2017-03-27 blocker review meeting: [1]

The decision was made to classify this bug as an AcceptedBlocker as it violates the following Alpha criteria:

"All release-blocking images must boot in their supported configurations."
