           Summary: pcmcia: trouble inserting network card and then network
                    unstability
    Kernel Version: 2.6.13-rc5-git4
            Status: NEW
          Severity: normal
             Owner: linux-pcmcia at lists.infradead.org

Most recent kernel where this bug did not occur: 2.6.12.4   
Distribution: Debian/unstable     
Hardware Environment: c.f. cardbus bridge in lspci output below + Enterasys   
RoamAbout pcmcia card (http://www.enterasys.com/products/wireless/RBTBG-AW/)   
Software Environment:   
Problem Description: pcmcia card not seen at first insert, seen at 2nd insert   
but then network instability (debian/waproamd searching for the AP every 2/3   
minutes).   
   
Under 2.6.13-rc* (I verified with 2.6.13-rc1 and also with latest as of today,   
i.e. 2.6.13-rc5-git4); if I insert my network card (driven by madwifi external  
module), using network works for some seconds, 1 mn max, and then the system  
seems to loose connection to the AP, debian/waproamd start to search again for 
an AP, network comes back; etc.  
   
I have seen nothing particular in /var/log/syslog except:  
  
os_wait_semaphore     : Failed to acquire semaphore[ebf6    
e5c0|1|0], AE_TIME 
 
I am unfortunately not at all a kernel hacker, don't know why this is 
happening - but I hope I can help to find!

Run 2.6.13-rc* serie and insert a network card in a similar h/w than mine
