[SOLVED] Kernel panic on network activity

Well, I have a rather serious problem. I seem to get a kernel panic every time there is any network activity. Here's the story:

I installed Gentoo 2005.1 using a full install CD, stage3, using a wired ethernet connection (eth0) for all internet activities. After some inital trouble, I recompiled my kernel so that it too could detect eth0 (besides the live CD's kernel I mean), and emerged ndiswrapper to use with the mrv8ka51.inf driver I have for my PCI wireless NIC. This is the Marvell W8300 chipset on the D-Link DWL-G510 (rev A) card - PCI ID "11AB:1FA6".

I then created /etc/init.d/net.wlan0 -> /etc/init.d/net.lo, and edited /etc/conf.d/wireless to include settings for encrypted connections, preferred APs, and whatnot, in compliance with my wireless network.

Now whenever I boot up, both eth0 and wlan0 are loaded. They both say they are connected (or at least don't show an error or red '*' during the init sequence), although I have nothing plugged into my eth0. Using `iwconfig` shows that it is connected to the correct AP, with the correct key and settings. However, when I try to ping google.com, there is an interminable silence, and when I try to ping my router (192.168.1.1), I get a kernel panic.

I know ndiswrapper recommends compiling the kernel with CONFIG_4KSTACKS turned off, but I couldn't find it in the menuconfig, so I just added it to the bottom of /usr/src/linux/.config before `make && make modules_install`.

Any ideas as to what's going on and how I should fix it? I'm a complete newbie at setting up linux (though I have used it at an abstracted level a couple of times), so please be explicit, and point out things that may seem obvious... sorry...

Thanks.

Running your new kernel, post the output of:

Oh, one detail I forgot to mention - the last line displayed on the screen during the kernel panic is "kernel panic - not synced" and then something about interrupts... because I remembered something about interrupts on the ndiswrapper site, I went and checked - turns out that they recommend using

All right, fair enough - I'll try out my original D-Link DWL-G510 Rev. A driver as well (I'm currently using the Asus WL-138G driver, which ndiswrapper's site recommends).

Any ideas as to where to put the "acpi=noirq"?

Thanks

o_O Well, I found a solution, which makes no sense to me, but what the heck, it works...

This is where I got the solution, if anyone is interested. So I guess it was simply a driver compatibility issue after all.

Thanks for your help, MrUlterior.
