High CPU usage with b43 driver (bcm4312 [14e4:4315])

linux-howto

http://www.linuxquestions.org – Hi, I was hoping somebody could help me out with this. My netbook came with a Dell 1397 WLAN mini-card, here's the chipset information: Code: 03:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01) I'm currently using the broadcom-sta driver, which kinda works. But I'd like to switch to the b43 driver so I won't have to rebuild any modules after a kernel update. The chipset is supported by the b43 driver since kernel 2.6.32, but when I use b43 a process called 'phy0' eats up about 30-40% of my CPU. I tried killing the process, but it just starts again. And when I try to 'rmmod b43' my system locks up. Any ideas? Thanks EDIT I'm using Slackware-Current, btw (HowTos)

memory video driver 3 years 15 weeks ago

I have have to write a video device driver, but rendering will happening in memory, not on a physical card. I already wrote a simple driver stripping out hardware piece code from an existent vodoo driver. I an install it, uninstall it but i dont know how to map it to a file /dev/mydevice_video

So my friend got new laptop with mobility radeon 5470. It's not supported by neither free nor proprietary drivers, so he is stuck with vesa - correct me if I'm wrong.

How can he achieve 1366x768 - resolution native for his lcd panel? Currently we're limited to 4:3, up to 1024x768 - scales ugly.

Tired of not knowing anything except Windows. Bought a Dell mini with Ubuntu 8.04 installed on it and I'm working on learning Unix from the command line. This Forum ought to be helpful once I get a little further along.

Hey guys. I'm trying to install the proprietary x86 driver for the ATI Radeon 9600 XT graphics card under Slack 13. I downloaded the file (a ".run" file), but when I try to install via "sh [etc.]" it unpacks the archive, then tells me my kernel is not supported.

hi, i have recently installed opengeu which is based upon ubuntu 8.04 but i need the deb package for the latest kernel as my terminal rejects any attempt of making it and without the kernel my net and few other bit dont work. if anyone could send me a link to it i would be most grateful

Hi everyone,

pata_serverworks driver 3 years 11 weeks ago

All,

I recently aquired a Dell Poweredge 600SC. It was loaded with Fedora 3.

I tried upgrading to 12, didn't work.

I tried upgrading to 8... it got hung on pata_serverworks driver.

Now trying to upgrade to 7, its doing the same thing.
