Bug Description
(For anyone coming to this bug for the first time, the current workaround is to add this to the kernel boot parameters: intremap=off)
I've used Ubuntu on this specific machine for years without problems, but starting with the 4.13 kernel that came with the 17.10 HWE and continuing into 18.04 kernels my computer would no longer boot, hanging at various screens:
- A blank screen with a flashing cursor
- A screen with this message:
Loading Linux 4.13.0.36-generic ...
Loading initial ramdisk ...
- A screen with kernel messages, ending in:
APCI: EC: interrupt blocked
I've encountered the bug in a number of kernels, including:
- 4.13.0-32
- 4.13.0-36
- 4.13.0-37
- 4.15.0-24
- 4.15.0-34
- 4.15.0-36
- 4.15.0-38
- 4.15.0-42
- 4.20.0-rc7
I was able to work around the issue by adding noapic to GRUB_CMDLINE_
GRUB_CMDLINE_
I'm not entirely sure of the consequences of this workaround, but one thing I've noticed is significantly reduced battery life.
This bug seems very similar to what's described here for the Thinkpad E485/E585: https:/
I'll attach screenshots of various times I've encountered this bug over the last year.
