See Item #2.

Summary:

Red Hat/Fedora uses a 4k stack size. Doesn't work well with ndiswrapper, or rather with the drivers you are trying to use with ndiswrapper.

That seems to be the stock response but it doesn't seem to apply to an x86_64 kernel. 32 bit (e.g., i686) kernels have:

CONFIG_4KSTACKS=y

in the kernel config file. The equivalent beasty doesn't exist in the x86_64 config file. Also, I built my 2.6.21 kernel by using the Red Hat/CentOS 2.6.18-8.1.1 kernel configuration file and did a "make oldconfig" which just prompts for how to handle changes in the kernel config from the old config file version. Nothing came up about the stack size (shouldn't have the way "make oldconfig" works) so I should have the same options set for my kernel. It works but the RH/CentOS kernel doesn't.

I'd prefer to stay with the standard kernel if possible but I need to be able to "fix" whatever is causing the reboot. If it's as simple as turning off some option, I can automate that. I'm just hoping it's not some patch that applies a 4K stack limit without even having the ability to turn it off.

Cheers,
Dave
