linux 3.1 problem with my wireless card (Intel iw 5100)
I tried to build linux 3.1 on two slackware boxes.
Everything worked ok with the fujitsu laptop that has the 3945 (Intel) card.
But I got a problem with the hp laptop with the wireless Intel 5100.
Code:
cat /etc/slackware-version
Slackware 13.37.0
Below are the results of the command (on the same machine---hp intel 5100)
Code:
dmesg | grep -i iw
After I booted with the newly built kernel 3.1:
Code:

With my current kernel (2.6.39.1):

I checked the version of the firmware. Looks up to date.
Of course I built the kernel by using
Code:
make oldconfig
...
So far I have no clue. Any idea, anybody?
Thanks

Reason: correcting errors
I got bit by this when upgrading my wife's laptop from 2.6.38 to 3.1.0 today (this was on Gentoo). I believe it's due to choosing to enable th new IOMMU options during "make oldconfig". I ended going back into "make menuconfig" and correcting it by choosing PCI_MSI as recommended above and that fixed my issue.
