Description of problem: A fc6xen host kernel hides the host ttyS0/ttyS1 ports from the 8250* drivers. This makes any devices connected there, like UPSs or whatnot, unreachable to the host OS. Version-Release number of selected component (if applicable): 2.6.17-1.2630.fc6 How reproducible: always Steps to Reproduce: 1. examine dmesg log 2. note how 8250 driver is not loaded, even for ttyS1 ... 3. try to load 8250 driver, note it fails
This may be a duplicate of bug #180126. I'll test some of the dom0 hacks suggested there ("xencons=off", "sync_console") and report back.
Booting the dom0 kernel with xencons=tty, then manually loading the 8250 driver works: it restores access to the host serial ports. Should this be documented or automated?
