Subject: CONFIG_4KSTACKS in mm2?

Is there a way of disabling CONFIG_4KSTACKS in 2.6.5-mm2?
Or to make it configurable?

"arch/i386/Kconfig" line 1498 of 1542 --97%-- col 8
config 4KSTACKS
def_bool y

you could just change that to 'n'

That's what I did (and it works) -- but it's not really intuitive or
even configurable (in the way of menuconfig or something).

Andrew Morton turned it on unconditionally on purpose for wider testing.

Yep. It doesn't work with Nvidia's nvidia kernel drivers. But what's
new :)

What's new is that I forgot to turn it off, I'd been running 2.6.5-cko1,
built 2.6.5-mm1, booted up and installed nvidia kernel for it. I ended
up with a trashed HD which needed reformatiing and a fresh install. I
don't know what symptoms I should have seen, perhaps nvidia failing to
work. I suspect it was a combination of 4K_STACKS and some hardware bug
for which I am going to change the motherboard, memory and Athlon CPU as
I've had odd hangs during boot. A few boots hung, finally I disabled
level 2 cache and it came up, so I think I will leave the next bootup
till the new stuff is installed. I previously had a hard drive that
would not boot fully after starting X with nvidia, though it's mountable
as hdc1 and I can get at all the stuff I need.

Sid.
