Linux tip, Fedora tip / howto: rmmod rtl8187 hangs
Try my online puzzle page with Calcudoku, Killer Sudoku and online Sudoku.
rmmod rtl8187 hangsI have a wireless adapter with a Realtek 8187 chipset, and use the rtl8187 kernel module under Fedora 8 (kernel 2.6.26).
Sometimes I'd get disconnected, and the only way to reconnect would be to remove the kernel module (and kill dhclient) and connect again:
The problem is, the machine would hang at rmmod rtl8187, CPU use would go to 100%, and even the reboot would hang at "unloading modules". This was a major annoyance.
The solution turned out to be this: the rmmod only works if wlan0 is up.
