Hi - I'm trying to get wireless running on CentOS 4.7 on a dual core laptop (latitude-e4500) for an employee. I'm having trouble with building dkms-ndiswraper-1.54-1.el4.rf - enclosed are the errors messages. The kernel was rebuilt to disable CONFIG_4KSTACKS. The errors prior to rebuilding the kernel are identical to the errors after rebuilding the kernel and rebooting - minus the error regarding the CONFIG_4KSTACKS. Basically I just typed make in the directory. I'm using dkms this time - I've never used it before. I'm under the...

....sourceforge.net] and then to use Windoze drivers. So I downloaded ndiswrapper and during the install, I received a warning message referring to "4K Stacks" and that NOT disabling 4k stacks can cause some drivers to crash. The docs went on to suggest I recompile the kernel to disable CONFIG_4KSTACKS. Question: For really like to stick to the stock CentOS-4 kernel and not create/use a custom one. Has anyone had a problem using the Linksys WPC54G Cardbus adapter + Centos-4 and NOT had to use a custom kernel? For that matter, since I haven't purchased the card yet, can I get a recommend...

...AN - USB - Stick Netgear WG111v3. ndiswrapper -i wg111v3 works. I can see ndiswrapper -l wg111v3: driver installed device (0846:4260) present But after modprobe ndiswrapper the system freezes. Troublshooting on ndiswrapper-sites says: It's a problem of "kernel is using 4K stacks (CONFIG_4KSTACKS)" Solution: recompile the kernel. That's no good solution. Is there a knowing "CentOS-like" solution for this problem? Thx Timothy

Hi list, After a lot of testing + troubleshooting, I guess I'm observing what I am now calling a regression with zaptel 1.4.10 (is it?) As such I call for peer feedback, before either asking Digium install support or filing a bug. Thanks in advance!

Hi: This series tries to implement tx batching support for vhost. This was done by using MSG_MORE as a hint for under layer socket. The backend (e.g tap) can then batch the packets temporarily in a list and submit it all once the number of bacthed exceeds a limitation. Tests shows obvious improvement on guest pktgen over over mlx4(noqueue) on host: Mpps -+%

This is an abbreviated version of an e-mail that I also posted to the ndiswrapper mailing list. Compressing the long story, I ran into the same problem using CentOS 5 as I had with Fedora Core 6 and ndiswrapper: my laptop (HP Pavilion zv6000 series with a Broadcom BCM43xx wireless NIC) would lock up or spontaneously reboot after a few hours if I brought up the wireless interface. I also
