Please share log and instructions to reproduce if possible. Also, if
possible, please share bisection log that led you to this patch.

I currently do not see how this patch would cause that, it only
increases the timeout duration.

I know that under QEMU TCG mode, there are occasionally timeouts in
the test simply due to QEMU being extremely slow or other weirdness.
