Actually, Warner's pccard work has little or nothing to do with this particular case. Depending on how the 'hot-swap' bay is implemented, it's probably hooked by the PnP BIOS as a 'docking station', or detailed by the ACPI data provided by the BIOS. Making 'hot plug' of these devices (hot swap is almost certainly not feasible) work will require proper newbus-ification of the ata and fd drivers, and some hooks to detect their departure/arrival. These are probably worth doing for docking station support as welll. Reprobe-on-resume is kinda tough; you need to refuse to suspend if any device that is marked 'removable' is open/configured (this has to include pccards) or similar... -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
