RockyLinux 8.7 updated kernel 4.18.0-425 crash

[RLucas]

Hi there,
I recentenly installed the last kernel update, and my system crashes.
Using previous kernel, 4.18.0.-37232.1, my system still works.

I tried Ubuntu 22 live with kernel 5.18, it works.
I tried RockyLinux 9.1 live, I get a Kernel panic.

I’ve had quite the same issue in january with CentOS Stream (I should not have updated my CentOS to Stream ).
One of the reasons I migrate my system to Rocky.
My PC is very old, it is powered by a 2009 AMD Athlon II X2 250 processor.

I check RHEL 9 CPU pre requisite, it is supported.

I would like to keep that machine running another couple of years.

Screen messages 8.7
…
kernel offset: 0x11e00000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff)

Screen messages live 9.1:

end kernel panic - not syncing: Attented to kill init! exit code=0x00007f00

That Athlon supports x86-64-v2?

El9 will require x86-64-v2 support

This won’t apply to us Rocky folks for a while but it’s a useful bit of information for forward planning. el9 will require your AMD or Intel 64 bit cpu to support a minimum of x86-64-v2. Here is a script to find out what you’ve got. #!/usr/bin/awk -f BEGIN { while (!/flags/) if (getline < "/proc/cpuinfo" != 1) exit 1 if (/lm/&&/cmov/&&/cx8/&&/fpu/&&/fxsr/&&/mmx/&&/syscall/&&/sse2/) level = 1 if (level == 1 && /cx16/&&/lahf/&&/popcnt/&&/sse4_1/&&/sse4_2/&&/ssse3/) level = 2 …

On Rocky 8 you can run /lib64/ld-linux-x86-64.so.2 --help to see the supported levels.

The 4.18.0-425 issue … are there earlier error messages in the output?

AS I wrote, my CPU is supported:
This program interpreter self-identifies as: /lib64/ld-linux-x86-64.so.2

Shared library search path:
(libraries located via /etc/ld.so.cache)
/lib64 (system search path)
/usr/lib64 (system search path)

Subdirectories of glibc-hwcaps directories, in priority order:
x86-64-v4
x86-64-v3
x86-64-v2

Legacy HWCAP subdirectories under library search path directories:
x86_64 (AT_PLATFORM; supported, searched)
tls (supported, searched)
avx512_1
x86_64 (supported, searched)

I just mentioned it to let you know that my hardware is not recent, at the very least.

I’ve got a picture with the full screen messages, but how can I post it ?

@RLucas

Subdirectories of glibc-hwcaps directories, in priority order:
x86-64-v4
x86-64-v3
x86-64-v2

They are listed for everybody. Note how the x86-64-v4 is in that list too.

The minimun that one should have for el9 is:

Subdirectories of glibc-hwcaps directories, in priority order:
x86-64-v4
x86-64-v3
x86-64-v2 (supported, searched)

This forum editor seems to have “Upload” icon after Bold, Italics, Link, and Code icons.

Rocky 8

Well, it seems I won’t use Rocky 9 with my actual hardware.
