This is a 'known bug', and requires a re-write of the way PCCARD probing is done to fix it. (This rewrite would also fix a number of other bugs as well, but there is no one interested in taking on the laptop issue to completion.) > - Sometimes the PCCard isn't detected if inserted (or the system is booted > with the card already inserted: I had a Windows 98 running just fine with > the card, shut down the machine, turned power off and on and rebootet > FreeBSD and the card wasn't detected the 1st time, only after a few > plug/unplug operations, the card was properly detected).

You're best bet is to look into the code in pccardd and figure out why it's not working. > - After unplugging/replugging the card, I get an > Slot x, unfielded interrupt (0) Expected. The software doesn't like the hardware disappearing underneath it, and there's really no acceptable way to make this not happen.

I think someone found that this was due to an extraneous 'cli' instruction in the APM bios, but since there are lots of them in the code I didn't know which one to remove. Attempts to contact the author of the email were ignored. :( > > This is stock 3.0-current, latest cvsup from yesterday. > Needless to say, it works on Windows 98 I can lockup my box pretty easily on Windows hot swapping 'active' cards as well. It's just harder because the OS is slower. :) Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
