Here is my list of syscalls tested. It's the same list as in
runtest/syscalls with the following tests disabled :

- clone*
- msgctl07
- profil101
- syslog*
- times03
- waitpid*

I've disabled them because they were blocking except for syslog
ones. The syslog ones were disabled because I didn't have any syslog
daemon in my chroot. I didn't look at the other tests but this can be
due to emulation bug or host bug. I need to run the same tests on the
host to be able to detect what's really due to qemu emulation.
(Please note that I was testing arm-linux-user on x86 host. I hope to
I'll find some time to do more tests).
