Well I upgraded to FC2 (from FC1) yesterday and all went well with the notable exception of ndiswrapper, which I use to drive my Intel 2100 card.

It compiles just fine, but loading the module with modprobe completely freezes the system.
I actually had to boot to safe mode and remove the lines from modprobe.conf & modules.conf to prevent a kernel panic.

To answer the obvious next question, I'm running the stock FC2 kernel (2.6.5-1.358 - i686).

On the ndiswrapper site, they make specific mention of disabling 4KSTACKS in 2.6.x kernels, however this 2.6.5 kernel doesn't even seem to have that option.

In googling it seems that folks with nvidia drivers are experiencing similar pains, and they all make reference to the following two configs:
CONFIG_4STACKS = n ( no )
CONFIG_REGPARMS = n ( no )

Thus at present I see my options as:
1. Download a non RH 2.6.6 kernel from kernel.org, and configure with the two aforementioned items disabled (if they exist!)
2. Disable REGPARMS in my current kernel & recompile.
3. Downgrade to 2.6.3 (where I'm fairly certain the 4KSTACKS option exists) and compile...Not too thrilled with going backwards.

Any opinions or other advice? Anyone have similar experiences and/or solutions?

Thanks,

Quint

Well, the good news is that by upgrading to the 2.6.6 kernel and disabling 4K stacks, the ndiswrapper is now back to a fully functional status.

Unfortunately the upgrade seems to have broken all of the redhat network configuration utilities...for example, when starting system-config-network, I get the following, can anyone make sense of this?

I'm on a fresh install of FC2 on my new T41 thinkpad with Centrino (Intel 2100) trying to get it working with the stock kernel. I've been butting my heads against it for a few days, but later on today I am going to copy down the error that I get when I insert the kernel module and my system goes down....

Turned out the problem with system-config-network I was having was related to the way I named my custom kernel. When I downloaded 2.6.6 and compiled it, I put two dashes in the "extra version". Oddly enough, that was enough to crash the utility. Once I renamed my kernel and recompiled, everything worked like a charm.

So in the end, for me, the upgrade from the Fedora 2.6.5-1.358 kernel to a kernel.org 2.6.6 kernel solved my problems with ndiswrapper.
