 If you have a new kernel that support mac80211 and includes the new rtl8187 driver then you **MUST** blacklist it otherwise the ieee80211 version of the module below will not work.  See [[r8187#blacklisting_mac80211_driver_version|blacklisting mac80211 driver version]] below.

 You MUST ignore the dBm and mW labels.  The value of "5" above is the actual value in the  0 to 35 range.  Unfortunately due to driver constraints, the "dBm (3mW)" are also displayed but must be ignored.

 Solution: This typically occurs after you have upgraded your kernel version. Delete the all the patch files and install a fresh version.  You should now be able to compile it successfully. Also ensure that you have matching kernel header files.

   * To remove them from system log files, edit /etc/syslog.conf or /etc/rsyslog.conf depending on your system.  Add "kern.!debug" to definition of each file receiving the debug messages.
+Another more radical approach is to comment out the kernel messages in the kernel source code.  This will also mean recompiling your kernel.
+Change net/core/skbuff.c in your kernel source:
+   void skb_truesize_bug(struct sk_buff *skb)
+   {
+         printk(KERN_ERR "SKB BUG: Invalid truesize (%u) "
+                "len=%u, sizeof(sk_buff)=%Zd\n",

+   EXPORT_SYMBOL(skb_truesize_bug);
+to:
+   void skb_truesize_bug(struct sk_buff *skb)

+   //             skb->truesize, skb->len, sizeof(struct sk_buff));
+   }
+   EXPORT_SYMBOL(skb_truesize_bug);
+This effectively eliminates the kernel from reporting the SKB BUG messages.

 SKA is not currently supported with the RTL8187 driver. There is no known workaround.
+===== WPA/WPA2 fails in managed mode =====
+On recent kernels, the patched driver fails to work in normal WPA/WPA2 mode.  In this case, use the patched ieee80211 driver for injection and use the mac80211 version for normal WPA/WPA2.  In order to do this you will have to blacklist the unwanted module based what you plan to use your system for.  IE For injection, blacklist the rtl8187 module.  For WPA/WPA2, blacklist the r8187 module.
