Then I looked in my box of cables and found I didn't have the right gender adapter, so I had to wait for that as well! Getting the card has been an education in kernel drivers - builtin vs. modules. I first had to realize that 'serial' is a builtin, so lspci -s [...] -k for my wifi card may say: 0b:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) Subsystem: Intel Corporation Device 1020 Kernel driver in use: iwl3945 Kernel modules: iwl3945 but the serial port only says: 0c:00.0 Serial controller: NetMos Technology Device 9922 Subsystem: Device a000:1000 Kernel driver in use: serial None the less, the serial port is a pci device, so it is found in /sys/bus/pci, not /sys/bus/platform. With that realization, the nagging suspicion that the card was not being initialized on all kernels was confirmed. I booted under pvops 2.6.32 (myoung), f15's 2.6.40, f16's 3.0.0-1, and rawhide's 3.1.0-0.rc1.git6.1, all of them as dom0 and baremetal (except the offending 3.1.0 can't boot as dom0), and the latter, baremetal, was the only one that initialized the card. Under all other systems, dmesg said: Aug 12 17:58:02 Insp6400 kernel: [ 0.735416] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled Aug 12 17:58:02 Insp6400 kernel: [ 0.756915] serial 0000:0c:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 Aug 12 17:58:02 Insp6400 kernel: [ 0.758492] serial 0000:0c:00.0: PCI INT A disabled but 3.1.0 said: Aug 12 18:06:45 Insp6400 kernel: [ 5.421588] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled Aug 12 18:06:45 Insp6400 kernel: [ 5.457800] serial 0000:0c:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 Aug 12 18:06:45 Insp6400 kernel: [ 5.481880] 0000:0c:00.0: ttyS0 at I/O 0xdff8 (irq = 19) is a ST16650V2 Similarly, on 3.1.0, the contents of /sys/bus/pci/drivers/serial is: drwxr-xr-x. 2 root root 0 Aug 14 16:51 ./ drwxr-xr-x. 28 root root 0 Aug 14 16:51 ../ lrwxrwxrwx. 1 root root 0 Aug 14 16:52 0000:0c:00.0 -> ../../../../devices/pci0000:00/0000:00:1c.3/0000:0c:00.0/ --w-------. 1 root root 4096 Aug 14 17:21 bind --w-------. 1 root root 4096 Aug 14 17:21 new_id --w-------. 1 root root 4096 Aug 14 17:21 remove_id --w-------. 1 root root 4096 Aug 14 16:51 uevent --w-------. 1 root root 4096 Aug 14 17:21 unbind where as all other kernels did not have the soft link.

Well, at least I had one system to debug my connections with - baremetal 3.1.0. So I fired up 'screen /dev/ttyS0 38400,cs8' on both my fedora 3.1.0, and another client, and everything worked fine. With this grub stanza: title Xen Dom0 w/debug console (3.1.0-0.rcx.gity.z.fc17.x86_64) root (hd0,1) #kernel /xen.gz cpufreq=xen loglvl=all guest_loglvl=all sync_console console_to_ring noreboot console=vga kernel /xen.gz cpufreq=xen loglvl=all guest_loglvl=all sync_console console_to_ring noreboot com1=115200,8n1,0xdff8,19 console=com1 module /vmlinuz ro root=/dev/mapper/vg_insp6400-lv_root SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 KEYTABLE=us console=hvc0 earlyprintk=xen debug loglevel=8 video.allow_duplicates=1 nomodeset module /initramfs where x,y,z = 3.1.0-0.rc1.git6.1.fc17.x86_64, and 'vmlinuz' and 'initramfs' are soft links to that kernel, I got the following serial console log.
