Hey all,

I'm running Xen pre-3.0 from FC4, rebuilt on a Debian system. (I needed support for 2.6.12 kernels, which they include, and I haven't been able to get anywhere else).

If I specify com1=<stuff> as a boot parameter for Xen, I am unable to access the serial port under Linux; in syslog, I get:

[    1.796999] WARNING: Failed to register Xen virtual console driver as 'ttyS0'

and if I try to read/write from ttyS0 I get I/O errors. I also get the above error if I remove com1=<stuff> from the Grub command line, but then the serial port works fine.

Any ideas? Is this something fixed in a more recent snapshot of 3.0? If so, anyone got patches to let me use a 2.6.12 kernel with recent 3.0? (I need 2.6.12 for a recent version of GFS.)
