>Organization:
Queen Mary and Westfield College
>Environment:
FreeBSD 3.1-RELEASE with PCCARD support
>Description:
The /etc/rc.pccard script on 3.1-RELEASE does not check
whether PCCARD support has already been loaded when loading the
pcic kernel module. If PCCARD support was also statically linked
into the kernel, the pcic code is loaded twice. This leads to
erratic and downright nasty behaviour from the PCCARD code.
People are complaining about this on a daily basis to the
-mobile and -questions mailing lists -- a description of the
problem and a simple workaround should be in the ERRATA.TXT file.
>How-To-Repeat:
Watch -mobile or -questions for the next person getting
bitten by this problem :)
>Fix:
Add something like the following to ERRATA.TXT:
o You've recompiled your kernel to include PCCARD support, and
set pccard_enable="YES" in /etc/rc.conf (just as you did for
previous releases). Now your PCCARDs don't work: the kernel
messages indicate that you have two card controllers, cards
are not recognised when they are inserted, etc.
Fix: The 'pcic' (card slot controller) code is getting loaded
twice; the two copies are conflicting with each other and
causing the symptoms described above. The fix is to _not_
enable the pcic devices in your kernel config file, ie.
# PCCARD (PCMCIA) support
controller card0
#device pcic0 at card?
#device pcic1 at card?
Leave the pccard_enable="YES" line in /etc/rc.conf -- the
etc/rc.pccard script does more than just load the driver
so it still needs to be run.
I believe that /etc/rc.pccard has been modified to detect
this condition and work around it in 3.1-STABLE.
