full syslog during boot
It's from efifb io mapping and it's merely a kernel warning about mapping the RAM pages, so no real Oops. In general, the recent AMD chip isn't fully supported with Leap 15.1 kernel, and you'll certainly have a better chance with Leap 15.2 kernel. You can install Leap 15.2 kernel on top of your system and see whether it works better. Yes, I agree it is not a proper "oops", but I don't know how to call it. It just says "cut here", not even a "please report this" ;-) I updated the kernel, and I am running now: cer@Telcontar:~> uname -a Linux Telcontar 5.3.18-lp152.10-preempt #1 SMP PREEMPT Wed Apr 1 11:48:53 UTC 2020 (ccee559) x86_64 x86_64 x86_64 GNU/Linux cer@Telcontar:~> I'm surprised at the "preempt" type.

full syslog during boot, with kernel from 15.2 (preempt)
You'd better keep using kernel-default. kernel-preempt is usable but not supported for Leap for now. And about the kernel warning: it's rather suspected as a BIOS firmware bug. The BIOS should have declared the region properly. So I'd recommend you to upgrade your BIOS if available. In anyway, the message itself is no serious problem, and unless you see no problem at boot, you can ignore it. Thank you :-) For some unknown reason, when told to update to newer packages on repo, it chose the preempt instead of default. I noticed when booting. cer@Telcontar:/data/storage_c/repositorios_zypp/LocalRPMs_15.1-15.2-kernel> ls kernel-default* kernel-default-5.3.18-lp152.10.4.x86_64.rpm kernel-default-base-rebuild-5.3.18-lp152.10.4.lp152.4.13.x86_64.rpm kernel-default-base-5.3.18-lp152.10.4.lp152.4.13.x86_64.rpm kernel-default-devel-5.3.18-lp152.10.4.x86_64.rpm cer@Telcontar:/data/storage_c/repositorios_zypp/LocalRPMs_15.1-15.2-kernel> ls kernel-preempt-* kernel-preempt-5.3.18-lp152.10.4.x86_64.rpm kernel-preempt-devel-5.3.18-lp152.10.4.x86_64.rpm cer@Telcontar:/data/storage_c/repositorios_zypp/LocalRPMs_15.1-15.2-kernel> I'll force back.

But the problem with efifb will likely remain with kernel-default, though. Although this appears more like a BIOS firmware bug that exposes the incorrect memory maps, I reassign the bug to our ACPI expert. Yes, Comment 7 was done with kernel-default and with updated bios. Thanks. Hi Robinson,
Could you please provide dmesg with the following kernel parameters?
debug loglevel=9 efi=debug
The most important is efi=debug, it will print out the EFI memory map. On the other hand, please also provide ACPI dump:
# acpidump > acpidump.raw
Thanks a lot!

Add the following kernel parameter: memmap=0x300000$0xe0000000 For grub2, it may needs escape character: memmap=0x300000\$0xe0000000 No response. Closed. |
