Maybe. Anyway, can you try this?

(1) Build current head-of-git QEMU from source, and check the bug is still
    present. (I expect it will be, because we have made no changes in
    this area since 7.0.)

(2) With that QEMU, gather strace output from both QEMU itself, and
    from the host kernel, like this:

    path/to/qemu-arm -strace -D qemu-strace.txt timertest

    strace -f -tt -o host-strace.txt path/to/qemu-arm timertest

    and send me the resulting qemu-strace.txt and host-strace.txt logs.

Hopefully those logs will have enough information that we can figure
out what's going wrong on your system.
