Public bug reported:
Running Ubuntu 18.04 / Mac OS High Sierra Dual Boot on Macbook Pro 11,1.
I've had a long standing kernel problem, that is still present for
Ubuntu's linux-generic 4.15.0-34 kernel.
Since roughly December the system has two kinds of boots: good and bad.
I had been running 16.04 until a few days ago. I was hoping an 18.04
update would get rid of this problem. The problem remains, both with the
canonical's 4.15 generic kernel and the 4.19 rc4 kernel. I even updated
Mac OS to High Sierra in hopes that would update any potential firmware
updates might resolve the issue.
No dice. Hope this bug report can get the ball rolling.
The Boots--------------
Good Boot:
5 seconds from power on chime to refind bootmanager, 5 seconds to kernel space,
10-15 userspace.
Bad Boot:
it takes about 20-30 to get to my boot manager after I select the kernel to
use, it takes roughly 50 seconds, most of that time is spent with the kernel
trying to assign an address to usb 2-3: my computer's SD Card Reader. Something
prevents it from doing so and it gives up after trying all 4 usb ports twice.
(Eats 40 seconds).
On a Good Boot the SD Card Reader works just fine. On a Bad Boot it is
completely nonfunctional.
When are Good Boot and Bad Boots?-------------
Cold Reboots are always Bad.
After a Bad Boot, a warm reboot is always Good.
A warm reboot after a Good boot is always Bad.
I've compared the dmesg logs between the different boots and they are
quite different. Something in the shutdown/reboot process is really
altering how the kernel behaves. Since the slowdown starts before the
boot manager I've been suspicious of the EFI. Checking EFI variables
between these two boots shows an EFI variable is present after a good
boot that is not present after a bad boot: usb-cr-rec-7c436110-ab2a-
4bbb-a880-fe41995c9f82. This appears to be a Mac specific setting. I
don't know what it does, but I can confirm that speeds up the boot
process when present, regardless of which operating system I boot.
I'm aware this might be an EFI issue that I might have to talk to Apple
about. However, Apple's kernel seems to handle the SD card reader
gracefully, rather than leave a 40 unresponsive blank screen whilst
booting.
I have attached the slow boot dmesg logs for Canonical's 4.15.0-34
kernel. The big gaps of kernel time are generally accompanied by lines
like
usb 2-3: device not accepting address 4, error -62.
I'd like to attach files for for current 4.15 Ubuntu and 4.19 Mainline fast and
slow boots, but there
only seems to be one attachment allowed.
