| |
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
