[Xen-devel] byg report : "console=com1" and "Unknown interrupt"

[Adam Sulmicki <adam@xxxxxxxxxxxx>]

hello,
        I'm booting xen on iTuner over serial console. It seems to me
        that it is bug that unless I explictly specify "console=com1"
        I get unhelpfull message "Unknown Interrupt" and halt (infinite
        loop).

sh-2.05b# /sbin/kexec -e
Starting new kernel
Unknown interrupt

        adding "console=com1" fixes this problem for me so I doubt it
        I'm going to look at it any closer, but I though I would to
        submit it any way in case someone wants to make the error message
        more obvious or something.
