--- Comment #1 from Siva Mahadevan <siva@FreeBSD.org> ---
I think there may be more to this bug report than I initially thought. I found
a new regression that possibly could be connected to the sys/net/if_geneve
testsuite.

In aarch64, I see a panic, both in jenkins CI[0] and locally (attached in this
bug as kyua test report dumps):

[0] https://ci.freebsd.org/job/FreeBSD-main-aarch64-test/2155/consoleText

I can reproduce it when running these two testsuites in parallel:
* sys/net/if_geneve
* sys/net/if_gif

Here's the reproducer (I ran at least 200+ runs to consistently reproduce
this):

bricoler freebsd-regression-test-suite --freebsd-src-git-checkout/url=/usr/src
--freebsd-src-git-checkout/branch= --freebsd-src-build/toolchain=llvm21
--freebsd-src-build/kernel_config=VIRT
--freebsd-src-build/machine=arm64/aarch64 --freebsd-vm-image/packages=
--freebsd-regression-test-suite/hypervisor=qemu
--freebsd-regression-test-suite/count=200
--freebsd-regression-test-suite/tests='sys/net/if_geneve sys/net/if_gif'

pouria@ are you able to reproduce this as well?
