Random segmentation faults when building for arm64 architecture

[Kees-T]

I am trying to build centec-arm64 at our Ubuntu 20.04.6 host. However building the slave docker images as part of the "make configure PLATFORM=centec PLATFORM_ARCH=arm64" fails with random segmentation faults, see:

> dmesg | grep aarch64
[ 5479.124295] aarch64-linux-g[256614]: segfault at 3067350 ip 000000000061c4a0 sp 00007ffc82d0bd78 error 4 in qemu-aarch64-static[401000+462000]
[ 7452.951572] awk[359050]: segfault at 2f88350 ip 000000000061c4a0 sp 00007ffced98cab8 error 4 in qemu-aarch64-static[401000+462000]

However the Azure builds of centec-arm64 is successful. So I am assume that it is related to my Linux host, so I like to know what Linux host is used for the Azure builds.

Note: I upgraded to Ubuntu 24, but observed the same random segmentation faults.

I Hello, I also encountered this problem. Have you solved it? If you have solved it, can you provide a solution? Thank you

After I realized that the Azure build was done on an ARM64 server I rented an ARM64 cloud server to do the build. At this ARM64 cloud server the build was successful.

Got it, thank you very much

You can try like this，It effect in my machine。
file:sonic-slave-buster/Dockerfile.j2
FROM {{ prefix }}tonistiigi/binfmt:qemu-v9.2.2-52 as qemu
FROM {{ prefix }}multiarch/debian-debootstrap:arm64-buster
COPY --from=qemu /usr/bin/qemu-aarch64 /usr/bin/qemu-arm-static

I tried this, but unfortunately in my case the random segfaults remain.

Ubuntu will automatically upgrade the kernel version,
do not let the kernel version upgrade
This effect kernel version:Linux ubuntu 5.8.0-43-generic #49~20.04.1-Ubuntu SMP Fri Feb 5 09:57:56 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
The newer kernel version does not match the qemu version
