I'll appreciate if you also reconsider using static variables in both 
variants of validate_mem() in drivers/pcmcia/rsrc_mgr.c.  The can cause 
the same error message when cardmgr is restarted.

The original message didn't describe the problem in details.  It's 
possible that the actual problem was in validate_mem().  For that to be 
the case, the problem would not appear initially after reboot or after 
pcmcia_core is reloaded.
