+It is possible to re-run a single test with enlarged timeout with \"TIMEOUTFACTOR=<factor> make test t=<test name>\". For example, \"TIMEOUTFACTOR=10 make test t=nss/tst-nss-files-hosts-multi\" will re-run nss/tst-nss-files-hosts-multi with ten times the original timeout.

+Additionally, some tests may fail with a relatively old CPU model (for example elf/tst-cpu-features-cpuinfo) or host kernel version (for example stdlib/tst-arc4random-thread).
