| jbicha | it looks like I need to re-release Ubuntu GNOME amd64, I didn't realize we needed linux-signed-generic for efi boot to work | 01:40 |
|---|---|---|
| slangasek | jbicha: you don't | 04:22 |
| slangasek | except on stgraber's hardware | 04:22 |
| slangasek | (this is an as-yet-undiagnosed bug in grub or shim; on reference hardware it boots unsigned linux just fine) | 04:23 |
| jbicha | ok, well we found a second case then, it's third hand though but I told them to file a bug | 04:25 |
| slangasek | ok | 04:25 |
| jbicha | what package should they file the bug against? | 04:25 |
| slangasek | mind you I'm not saying you can't reroll the images, I'm just saying it's not true that you need linux-signed-generic for efi boot | 04:26 |
| slangasek | package - grub2 | 04:26 |
| jbicha | why does ubuntu amd64 have linux-signed-generic pre-installed though? | 04:26 |
| slangasek | furthermore, the only reported failures to date are with booting unsigned kernels under secure boot... is this user running SB? | 04:27 |
| slangasek | because linux-signed-generic lets us hand off to the kernel without calling exitbootservices first, which allows leveraging of some EFI quirk handling in the kernel early boot | 04:28 |
| slangasek | (e.g., the not-yet-landed fix for bug #1065263) | 04:28 |
| ubot2 | Launchpad bug 1065263 in linux (Ubuntu) "wrong stride for efifb on some systems" [High,In progress] https://launchpad.net/bugs/1065263 | 04:28 |
| ScottK | slangasek: I'm now convinced that multiarch in python3.3 is going to matter a lot more for migration than the actual changes in 3.3. | 04:43 |
| ScottK | Unfortunately I think I mostly understand the PyQt build system now. | 04:45 |
| ScottK | I had to waste a lot of brain cells on it in order to zero in on a two line fix. | 04:45 |
| micahg | ^^ rejected since I forgot the bug # | 05:28 |

| cafetiere | slangasek: any amd64 kernel lets you hand off without exiting boot services signed or not | 16:57 |
| cjwatson | but grub will not actually do so unless it's signed | 16:59 |
| cjwatson | so kind of moot | 16:59 |
| cjwatson | (well, I forget if it will allow that if SB is off) | 16:59 |
| slangasek | ScottK: multiarch> doesn't surprise me | 18:48 |
