I don't like to see --force gotta RTFM before I run this.

Found this as well.

2014-01-04 20:28:32 -0500 asked a question Troubles with GRUB2 and EFI

I recently upgraded a computer to Fedora 20. Previously I had left a Windows partition on the system but choose to disable secure boot and efi leaving that partition unusable. When I updated, I chose to get the Windows partition working because its user required a couple programs (not too frequently, but once in a blue moon).

When the kernel was updated on the fresh install, it added a new boot option to the bootloader, however booting the new kernel throws an error along the lines of:

alloc magic is broken at 0xe71232231: 0
Aborted. Press any key to exit.

The original boot entry (3.11.10-301.fc20.x86_64 according to uname) still works as well as the Windows boot entry. However, the two new kernel entries throw the error above. Does anyone have an idea what I could try to get the new kernel options to work?

2013-02-21 15:51:30 -0500 answered a question Can someone help me choose a distro to learn programming?

I'd suggest learning to use yum from the command line. The commands are pretty much the same as apt on Debian/Ubuntu.

There is a package labeled monodevelop. I found it by using yum search. To install the package type sudo yum install monodevelop. There is a package group called @development-tools to install GCC and the like.

Debian/Ubuntu apt-get install packagename apt-cache search packagename

Fedora yum install packagename yum search packagename

Likewise, you can use iptables for a firewall. Search yum for a front end if required. (Just search iptables, anything that includes the keyword will show up in the results).

I'm sure there's a way to create local repositories. I am not sure how you'd accomplish that. Google is your friend.

It appears your kernel is newer than the one supported by the version of that driver. The driver that comes by default should work.

If you really want to use the driver you download please apply the patch found here ( you must register to download the patch.

Altough, i suggest you remove the new driver you installed, un-blacklist the rtl8192cu, and reboot.

And then show us the problems you have. Also update to a new kernel if avaiable.

Patch worked. Thanks for the direction!

For anyone that needs to fix this:

Extract the driver latest driver (released 2012/11/12), extract the archive in the directory "driver", apply patch "patch -p1 > use _ kthread_run.patch", make/make install, and finally "modprobe 8192cu".

I believe I'm running the newest kernel in the repo, uname -r says 3.7.6-201.

Basically. The light is constantly on (Solid not blinking). It scans for networks. When you click one it will ask for the password. Then it idles for about 30 seconds and asks for the password again.

I recently upgraded my laptop to Fedora 18. The drivers included for my card did not work. The connection light stayed on. After entering a password, it idles and then asks again. I downloaded the latest drivers from realtek and blacklisted the modules included (rtl8192cu)

However, I'm getting an error attempting to modprobe the new driver (modprobe 8192cu).

Here's the end of the script.

Compile make driver ok!!

Authentication requested [root] for remove driver:
rmmod: ERROR: Module 8192cu is not currently loaded
Authentication requested [root] for insert driver:
insmod: ERROR: could not insert module 8192cu.ko: Unknown symbol in module
Authentication requested [root] for install driver:
install -p -m 644 8192cu.ko  /lib/modules/3.7.6-201.fc18.x86_64/kernel/drivers/net/wireless/
/sbin/depmod -a 3.7.6-201.fc18.x86_64

The Setup Script is completed !

modprobe: ERROR: could not insert '8192cu': Unknown symbol in module, or unknown parameter (see dmesg)

Dmesg resuls in

[ 5598.806849] 8192cu: Unknown symbol kernel_thread (err 0)

Here's the lsusb

Bus 001 Device 010: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]

Any ideas?
