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.
