[Bug 839019] Re: bringing up 10ec:8185 wifi module freezes the system
Same hardware here:
$ lspci -nn | grep 8185
01:0d.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller [10ec:8185] (rev 20)
$ uname -a
Linux boss 3.16-3-686-pae #1 SMP Debian 3.16.5-1 (2014-10-10) i686 GNU/Linux
Mainline 3.18-rc2 same problems apply. Found a hack / workaround is to
wrap iowriteNN with udelay()'s ; or to use ndiswrapper will also make
the device functional. Distro should probably blacklist the driver until
a proper fix is decided.

Title:
bringing up 10ec:8185 wifi module freezes the system
Status in The Linux Kernel:
New
Status in “linux” package in Ubuntu:
Incomplete
Status in “linux” package in Fedora:
Unknown
Bug description:
When 10ec:8185 module is modprobed this causes a complete freeze of
the system.
This issue is severe for two reasons:
* My computer is unable to connect to the network via wifi through a native linux driver;
* because 10ec:8185 is modprobed at startup, the liveCD will show a black screen without any error message.
Affected Ubuntu releases: Intrepid, Jaunty, Karmic, Natty, Oneiric,
Precise beta 1
Workarounds:
* ndiswrapper:
* works on Intrepid and Natty but not on Jaunty
