It is not being used on my machine per "lsmod". Did you try loading this original i8k driver? Did it work? What are the contents of /proc/i8k then? If the original works and mine fails, please send me the two .ko files in private and I'll try to figure out how they differ. Even better if you can get the exact kernel sources used by Fedora to build your running kernel so that I can also compare the source code (the source file is drivers/misc/i8k.c in the kernel tree.) > (2) Run "depmod -a" > (3) Build the new "i8k" module, but leave it where it is built > (4) Reboot, just to be certain the legacy "i8k" module isn't being loaded > (5) Copy the new "i8k" module to /lib/modules/`uname > -r`/kernel/drivers/hwmon > (6) Run "depmod -a" again > (7) Run "modprobe -v i8k" Note that you could simply use insmod with full path to the new module, so you don't have to install it. > At this point I get Console messages and a crashdump to Syslog.

That is not normal behavior. With the kernel crash you got, it's nor surprising that anything related to kernel module loading or unloading will hang. > Harry, is your Dell machine a single CPU or a dual-CPU system?
