Linux Kernel 2.6.15...

Loading the 802.11 driver via ndiswrapper?


The system suddenly is under such high system load I was watching individual lines of the screen get redrawn. Pixel by pixel.

Trying earlier kernels and earlier ndiswrapper versions didn't seem to change the behaviour.

So... I've apparently found an interesting... bug. And unfortunately one I couldn't debug... honest, I tried, but I couldn't figure out the first step towards trying to diagnose where this was bogging down.

And the kicker?

It's apparently a side-effect of upgrading the BIOS on my laptop to fix a clock-skew error I was running into. Joygasm.

So... for now I dumped a quick install of Windows on the boxen again for the moment. There's some wierd interaction between the clock-skew BIOS fix that was recently released, and 2.6.15 in combination with the SDHCI patch and ndiswrapper that causes no errors, but puts the system under such high load (I'm guessing interrupt load) that it can't even get enough time to redraw the screen fully.6 commentsLeave a comment
