+###
+### With "smart scheduler" enabled, Xserver sets up an itimer to
+### periodically receive SIGALRM from the kernel while the server is doing
+### a socket I/O and processing commands from X clients. When the signal
+### arrives while Xserver is in pixman_composite_src_8888_8888_asm_neon()
+### or any similar functions from libpixman, the process fails to return
+### from the signal handler and exits with status code 22 (EINVAL) due to
+### kern/58149. These functions misalign SP while doing some SIMD stuff,
+### thereby trigger the kernel bug.
+###
+### Disabling itimer can avoid the problem but there might be a performance
+### regression.
