Slow boot on rocky linux 10 latest kernel
-
Can reproduce on Fedora 44 and Alpine Linux (6.18.22-0-virt).
But doesn't occur on Debian 13 (6.12). -
-
@acebmxer which kernel version you have in your Debian guest (uname -a) ?
-
This is on fresh install Debian 13 deployed from XO Hub - 6.12.38+deb13-amd64. I do not see this behavior on Ubuntu.
after update 6.12.90+deb13.1-amd64
still happens.
-
@acebmxer I don't observe the same issue on Debian 13 Cloud-Init (both 6.12.38+deb13-amd64 and updated 6.12.90+deb13.1-amd64).
Though it still takes some time to boot (especially at loading the ramdisk) but it's not related to this pv spinlock issue and mostly a "BIOS guest" related issue.
But I'm testing on a Intel machine. -
Hello,
To gave more details abouit my case:
- XCPNG: 8.3.0
- CPU:
AMD EPYC 4464P 12-Core Processor - Kernel:
6.12.0-211.18.1.el10_2.x86_64
-
I was going to suggest it might be a amd issue. I can try later on work host that are intel.
-
@TeddyAstie These spinlock events that cause slow boot also happen on my Debian VMs. Also AMD Epyc CPU in my case.
I noticed that this only happens for UEFI enabled VMs. VMs booting in BIOS mode do not have this issue.
-
@MajorP93 can you give the kernel version of all the affected vs non-affected guests ?
-
I can reproduce on Debian 13 with stock kernel and a Ryzen 5 7600.
