This happens on an ultra-small laptop with no physical serial ports, but I suspect the behavior would be the same with any laptop using a pcmcia/cf GPS card (since the serial port doesn't exist until you plug the card in). When I plug in the GPS card in this case, /dev/ttys0 gets created just fine, but the GPS isn't usable until the serial port gets configured by a nice setserial command. I'm currently using: setserial /dev/ttyS0 port 0x03f8 irq 0 autoconfig Without the above command, there appear to be IRQ issues: Aug 5 14:41:08 minitux 0.0: ttyS0 at I/O 0x3f8 (irq = 3) is a 16C950/954 Aug 5 14:41:12 minitux irq 3: nobody cared (try booting with the "irqpoll" option) Aug 5 14:41:12 minitux [<c0141c3a>] __report_bad_irq+0x2a/0x90 Aug 5 14:41:12 minitux [<c01413d9>] handle_IRQ_event+0x39/0x70 Aug 5 14:41:12 minitux [<c0141d60>] note_interrupt+0xa0/0x100 Aug 5 14:41:12 minitux [<c0141508>] __do_IRQ+0xf8/0x120 Aug 5 14:41:12 minitux [<c01057c9>] do_IRQ+0x19/0x30 Aug 5 14:41:12 minitux [<c0103a92>] common_interrupt+0x1a/0x20 Aug 5 14:41:12 minitux handlers: Aug 5 14:41:12 minitux [<c0250010>] (serial8250_interrupt+0x0/0x150) Aug 5 14:41:12 minitux Disabling IRQ #3 Once the above setserial command is issued, gpsd (both old and new) can connect and give useful data. Obviously the normal rc.serial thing doesn't work since the device doesn't exist until the card is plugged in, so it seems to me pcmcia should be able to handle this without user intervention. According to google and the pcmcia docs, there are some config options that can be added to the /etc/pcmcia stuff, but it doesn't seem to work with my current configuration. The card itself shows as "Compact Flash GENERIC" or some such, but it won't modify as per the docs either, so I'm not sure exactly what's hosed up, missing, etc. Maybe it should have a Gentoo-ized config file, or at least an example somewhere, since it took me several hours of googling, reading, fiddling, and emerging to get this working. I expect there are several people with more pcmcia expertise than I have (since I'm not even sure if hotplug is involved or not :) so post away, please... sys-apps/hotplug-base - 20040401 sys-apps/hotplug - 20040923-r2 sys-apps/pcmciautils - 014 virtual/pcmcia - 2.6.13 Linux minitux 2.6.16.20 #3 SMP PREEMPT (vanilla-sources) also 2.6.17.7 vanilla plus PPS patches Don't mind the AMD64 stuff in the info below; it's really a Transmeta Crusoe mounted to my desktop as an exernal drive.

No takers?
Still present in 2.6.19?
