[Xen-devel] ttyS0: LSR safety check engaged!

["kyle.ma83" <kyle.ma83@xxxxxxxxx>]

 

Hi everyone

 

When I use xen-3.2.0 and linux-2.6.18 domian0 and debug xen with gdb stub, I failed.

 

dmesg |grep tty always get :

 

serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

00:06: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

ttyS0: LSR safety check engaged!

ttyS0: LSR safety check engaged!

ttyS0: LSR safety check engaged!

ttyS0: LSR safety check engaged!

 

my grub is :

 

kernel          /boot/xen-3.2.0.gz hap com1=115200,8n1 console=com1H gdb=com1L

module          /boot/vmlinuz-2.6.18.8-xen root=/dev/sda1 ro xencons=off

module          /boot/initrd.img-2.6.18.8-xen

 

I use a DELL PowerEdge server with Intel cpu, I don't what is the reason. when I use the same server and boot linux kernel , and no problem .

 

In grub I change many times with xencons=off or with nothing etc. but the problem is the same ttyS0: LSR safety check engaged!

 

Could anyone help me on this?  I really appreciate much.
