Follow-ups
--- Sonic Zhang 2011-11-30 01:59:49
Can't replicate manually via ttyS0.
--- Vivi Li 2011-12-05 01:09:33
No such bug in 2010r1 branch via ttyUSB0.
But it does exist in 2011r1 branch.
--- Sonic Zhang 2011-12-06 02:42:43
Fixed.
local_irq_save other than local_irq_disable.
--- Vivi Li 2011-12-08 01:12:48
OK now.
Close it.
