Description Luis Correia 2018-01-07 19:32:11 UTC
After updating tumbleweed from kernel 4.14.9 to 4.14.11, the system stops booting. It gets stuck during the boot splash and after a minute or so, the system resets.

Booting with 4.14.9 still works.

Starting 4.14.11 with the "nopti" option works and the system boots normally, so I assume it is due to the KPTI patches.

Hardware specs:

CPU: AMD FX-8320 8 Core
GPU: Two AMD R9 290X's
M/B: Gigabyte 990FXA-UD7 (UEFI)
PCIe Cards: Creative X-Fi & HP P400 (SAS RAID)

The boot drive is an SSD with BTRFS and the system has several other HDD's connected (EXT4, BTRFS & NTFS), along with a HP LTO tape drive and a second SSD with Windows 10.

Similar symptoms are reproted when a 32bit binary is run on AMD processors.

1) could you check 4.14.12 from Kernel:stable?
2) try to boot into text mode and see if you can capture the crash?

Although also related to KPTI, I'm not sure if the bug is the same as bug 1074869. As far as I know, no 32 bit binaries are loaded at startup (it is a fairly recent installation).
I will have access to the system at the end of the day and will provide boot logs / 4.14.12 results.

Sure, if it turns out to be a different issue, feel free to reopen this one.

After comparing a successful boot output with a failed one, it seems this bug is indeed a duplicate. The system had TeamViewer installed and it was hanging right before the TV module started. I believe TeamViewer runs in Wine, so it was probably trying to load wine which would crash the system. Removing TeamViewer solved the issue.
