[2679323.928221] [<000002aa39883214>] 0x2aa39883214
Triggered by the very same test, but NOT when I just run the three commands
I identified. It really seems my manual commands block on these syscall things
before I reach the actual issue.
Note This is a Hirsute container on a Focal host. There might be issues
between the new glibc using new stuff the kernel can't handle :-/
But the tests on the autopkgtest Infra happen on a current Hirsute kernel.
=> Theory III: Broken by new new glibc 2.33 (as we had other such cases)
But why is it then only happening when testing the new dpkg?
