Subject: [PATCH RESEND 0/2] two serial_core suspend/resume fixes
Date: Sat, 21 Aug 2010 15:14:40 +0800	[thread overview]
Message-ID: <1282374882-6651-1-git-send-email-jason77.wang@gmail.com> (raw)

Sorry for resending this thread. Last thread is forgot to CC
Greg Kroah-Hartman.

The [1/2] fix this situation:
we set no_console_supend and console=ttyS0 to bootargs, then bootup
the kernel, the boot logs will print out from ttyS0. When we execute
echo mem > /sys/power/state, the system will suspend, we press a
key(or other wakeup trigger) to resume the system, but the ttyS0 can't
work anymore.

The [2/2] fix this situation:
we set console=ttyS0 to bootargs, then bootup the kernel, the boot
logs will print out from ttyS0, this time we set ttyS1 as tty and
login for shell. When we execute echo mem > /sys/power/state, the
system will suspend, we press a key(or other wakeup trigger) to
resume the system, but the ttyS0 can't work anymore.
