Description Albert Ferrero 2021-03-05 07:54:20 UTC
Laptop is Dell Inspiron 3195 running AMD A9-9420e RADEON R5, this system has the integrated AMD graphics. System is using systemd-boot and is booting into an F2FS file system.

Upgraded linux package (5.10.16.arch1-1 -> 5.11.1.arch1-1). On reboot of system, immediately after systemd-boot, system appears to hang and do nothing. No log entries are recorded in journalctrl. Attempted to modify the systemd-boot kernel parameters by adding "debug ignore_loglevel earlyprintk=efi,keep log_buf_len=16M" but nothing is displayed to the screen. The systemd-boot loader goes blank and nothing is displayed on the screen. This happens every time. The power button is responsive, so I don't have to long press the power button to get it to power off, a quick press will turn the computer off, suggesting that something in the system is responsive.

Resolution so far is to downgrade to 5.10 kernel.
Comment 1 Albert Ferrero 2021-03-05 07:55:27 UTC
Working with Arch Linux distribution to help troubleshoot issue. Can see link at https://bugs.archlinux.org/task/69757?project=1&order=lastedit&sort=desc
Comment 2 Albert Ferrero 2021-03-05 07:55:46 UTC
Observed hang condition with newer 5.11.2 kernel that was released.

x86/io_apic: Cleanup trigger/polarity helpers

'trigger' and 'polarity' are used throughout the I/O-APIC code for handling
the trigger type (edge/level) and the active low/high configuration. While
there are defines for initializing these variables and struct members, they
are not used consequently and the meaning of 'trigger' and 'polarity' is
opaque and confusing at best.

Rename them to 'is_level' and 'active_low' and make them boolean in various
structs so it's entirely clear what the meaning is.

Comment 4 Albert Ferrero 2021-03-09 03:19:42 UTC
I tested with 5.11.4 kernel and observe the same behavior, the system hangs on boot.

I also observed that booting with either acpi=off or iommu=off will allow the system to boot and get to a log in prompt, but neither parameter is ideal since, if I specify iommu=off the system's performance is degraded and kernel panics on shutdown and if I specify acpi=off several components will not function (like wifi).

That commit is known broken, fixed by:

    x86/ioapic: Correct the PCI/ISA trigger type selection
    
    PCI's default trigger type is level and ISA's is edge. The recent
    refactoring made it the other way round, which went unnoticed as it seems
    only to cause havoc on some AMD systems.
    
    Make the comment and code do the right thing again.

If you're bisecting and have a27dca645d2c in your tree, apply the fix manually. Otherwise you're probably bisecting the *wrong* breakage.
Comment 6 Ari 2021-03-25 12:56:53 UTC
I have the same issue running Fedora 33 which just recently upgraded from 5.10.23 to 5.11.[7|8]. Both those new 5.11 kernels fail to boot on my Dell Precision 7510
Comment 7 Albert Ferrero 2021-03-27 01:47:29 UTC
Good news, I just tried the 5.11.10 kernel and I'm able to boot the Dell Inspiron 3195 without issues.
