Hi,
Starting with 4.6-rc1, a sleep 1 doesn't return :
execve("/bin/sleep", ["sleep", "1"], ["USER=root", "SHLVL=1",
"OLDPWD=/var", "HOME=/", "TERM=vt102",
"PATH=/sbin:/usr/sbin:/bin:/usr/bin", "SHELL=/bin/sh", "PWD=/"]) = 0
uname({sysname="Linux", nodename="LNS",
release="4.5.0-09406-g46e595a17dcf", version="#72 Tue May 10 15:41:34
CEST 2016", machine="armv5tejl", domainname="(none)"}) = 0
brk(0) = 0x153000
brk(0x153d20) = 0x153d20
set_tls(0x1534c0, 0x14d1e4, 0, 0x153d20, 0x14e368) = 0
readlink("/proc/self/exe", "/bin/busybox", 4096) = 12
brk(0x174d20) = 0x174d20
brk(0x175000) = 0x175000
getuid32() = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL, [], 0}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({1, 0},
And the heartbeat led doesn't blink anymore (full on), as if the
timers never fire.
The platform is an AT91SAM9G35-CM.
