What? There's more kernel apps than just ndis network drivers that

Which is why ndiswrapper needs to get fixed to work with 4K stacks.
ndiswrapper is the thing that's doing the wierd stuff, it needs to
adapt to the kernel, not the other way around. The reasons to use 4K
stacks are strong enough that they are not made up for by the fact
that ndiswrapper currently would like to have more stack space.
The NDIS drivers require the 8K stack, not ndiswrapper.
Windows apparently has 12K of kernel stack for drivers.. in that case
even 8K of stack in Linux would not necessarily be enough. If
ndiswrapper wants to run Windows code in the kernel with any amount of
reliability it should be providing its own stack which is the size
that the code expects.
My laptop is a Compaq and there isn't a Linux driver for the
wireless. I also discovered Fedora Core 4 won't install
on a Compaq Presario with SATA (stacks crashes).
How do you know this is related to the stack? Did you report this as a
bug?
Because I use MDB, a kernel debugger I wrote that inserts beneath Linux
via DRLX or inside of it, and I watched it crash in the Linux SCSI
code. There's code in Linux proper that also walks off the end of the
stack. No I did not report it. But now I have.
