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. 2009-09-02 kyle.ma83 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I really appreciate much.You may need to configure ttyS0 (COM1) on Xen''s command line. For example, com1=115200,8n1 That will set Xen up on that serial line at the correct baud rate etc, and also prevent dom0 kernel from using it. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
