[elrepo] [elrepo-devel] Broken kmod-compat-wireless package

[Roy Bonser]

Thanks for the info. I saw the error, I just wasn't sure it was actually
looking in /lib/firmware since the file exists there.

Here is the info you asked for:

# lsmod | grep firmware
compat_firmware_class     7614  1 b43
compat                 26336  6
b43,mac80211,cfg80211,bcma,ssb,compat_firmware_class

# lsmod | grep b43
b43                   395120  0
mac80211              286661  1 b43
cfg80211              193492  2 b43,mac80211
bcma                   29837  1 b43
ssb                    59632  1 b43
compat_firmware_class     7614  1 b43
compat                 26336  6
b43,mac80211,cfg80211,bcma,ssb,compat_firmware_class
mmc_core               77140  3 b43,ssb,sdhci

Thank you for your time on this.
