Hi Robert, I didn't understand totally what was going on. It seems like there were 2 problems. 1) There was a NULL dereference bug, which locked up the system and made the LEDs blink. 2) That somehow got fixed but the "wicd" wireless management program still didn't work. You were able to fix this by forward porting the driver from 3.1 to 3.2. It wasn't clear to me how you fixed the NULL deref. It turns out that it's really easy to fix NULL derference bugs. If you compiled the kernel with CONFIG_DEBUG_INFO=y you can run gdb on the .ko file. Here the instructions: http://wiki.samba.org/index.php/LinuxCIFS_troubleshooting#Oopses I think another option maybe is to use the `addr2line` with the RIP value? addr2line -e drivers/staging/rtl8712/r8712u.ko -i ffffffff8104f740 Once you know the line which crashed, it's normally easy for us to debug. regards, dan carpenter
