Description Rick van Rein 2000-04-17 02:28:51 EDT
My Dell laptop has been running 6.1 for about 4months, and I just upgraded
to 6.2 using an iso CD.  I have two CARDBUS ports on my Inspiron 7000, but
for some reason Linux is only able to assign interrupts to one of them at a
time.  I have a scsi card and a 3com ethernet card.  I was unable to track
the problem when booting with dmesg, but when I remove and replace the card
running dmesg provides this message:

 cs: cb_free(bus 32)
cs: cb_alloc(bus 32): vendor 0x9004, device 0x6075

I hope this provides some use for you.  If you need any more information,
please let me know, and I am completely willing to help in any way

This is a bug in the pcmcia package.  Later pcmcia packages are known to solve
this problem, but have not yet been fully tested for release purposes.  This
will be fixed with the next upgrade of the pcmcia package in the Red Hat

Any progress on this?  I realise you're all busy guys...but we have had quite a
few kernel updates over the past couple of months, and still no pcmcia-cs
update.  Thanks!

Hi Doug.  This is a severe bug that really deserves a bugfix update.
I simply cannot use RH6.2 on any of our laptops - the driver locks
them all solid :-(
