Hi All, When I'm booting my card while keeping connect to serial port,
everything is ok.
However, when I issued "reboot" command and disconnect connection to
serial port and
waited for several minutes, shell (bash) hanged. Finally I found it
hanged in following line
of /etc/init.d/rc.
stty onlcr 0>&1
Then I replace this line in /etc/init.d/rc with "strace stty onlcr 0>&1"
and got following cached
output. However sys_ioctl of kernel wasn't called ever.
brk(0x1003b000) = 0x1003b000
brk(0x1003c000) = 0x1003c000
ioctl(0, TCGETS, {B9600 opost isig icanon echo ...}) = 0
ioctl(0, TCGETS, {B9600 opost isig icanon echo ...}) = 0
ioctl(0, TCSETSW
