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

Perhaps the VGA-probe code needs fixing for your system? -- Keir ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
