Description Lendon Adams 2009-01-07 04:34:24 UTC

Description of problem:
The 4k stacks in the Fedora kernel cause freezing and kernel panics with my RTL8185 under ndiswrapper when doing modprobe ndiswrapper. The user has to pull a hard reset due to a complete lock-up, the fix was to compile a custom kernel without 4k stacks.

Version-Release number of selected component (if applicable):
This happens with Fedora 9 & 10 I am using 2.6.27.9-159

How reproducible:
Very

Steps to Reproduce:
1. Install Fedora
2. Install Ndiswrapper and RTL8185 driver.
3. Enter modprobe ndiswrapper

Expected results:
8k stacks by default.

Comment 1 John W. Linville 2009-01-07 19:00:27 UTC

ndiswrapper is unsupported and will continue to be unsupported.  We certainly aren't going to use bigger stacks just to make ndiswrapper work.

Did you try the rtl8180 driver that is in the stock kernels?
