Reopening this bug since i can still reproduce it on fedora 19. https://bugzilla.redhat.com/show_bug.cgi?id=864906 More info on the problem in the above bug report, although i'm only reopening this one. In trying to debug this in prior fedora versions i encountered a problem with the debug options on the RTL cards. Since then debug kernels are supposed to have RTL_WIFI_DEBUG option compiled, but it still doesnt. cat config-3.10.9-200.fc19.x86_64.debug | grep RTL CONFIG_USB_RTL8150=m CONFIG_USB_RTL8152=m CONFIG_RTL8180=m CONFIG_RTL8187=m CONFIG_RTL8187_LEDS=y CONFIG_RTLWIFI=m # CONFIG_RTLWIFI_DEBUG is not set Acording to this bugzilla entry debug kernels should contain the relevant options to debug. https://bugzilla.redhat.com/show_bug.cgi?id=889425 Something like this I guess:
diff --git a/Makefile b/Makefile

Josh/Kernel folks, I noticed a couple of other discrepancies (i.e. in debug we are missing MAC80211_MESSAGE_TRACING). Would a patch fixing them all + sorting
them in both Makefile and Makefile.release be ok?
Adding John to CC. I'll look at the RTLWIFI_DEBUG today. For MAC80211_MESSAGE_TRACING, I think we left that off on purpose because it can be very spammy and make things even slower on debug kernels than they already are. I could be misremembering though. John, any thoughts on this option for debug/rawhide kernels? Josh, I think you have it right re: MAC80211_MESSAGE_TRACING. OK, I looked at this. The config options are correct on 3.11 based kernels. RTLWIFI_DEBUG is set on -debug kernels and not on release kernels. There's nothing to really fix there. Hohum not sure at which branch I looked then. Sorry about that. Johnny, can you close this BZ please? Closing since the debug options are now present in the debug kernel. Thanks all for the help. |
