Hi

I just had to compile kernel for zipslack for 386 because
it's default has some problem with *WP
I chose linux-2.4.27 tree.
Sure i did it on other machine:

processor : 0
vendor_id : AuthenticAMD
cpu family : 5
model : 6
model name : AMD-K6tm w/ multimedia extensions
stepping : 2
flags : fpu vme de pse tsc msr mce cx8 mmx

I did

make mrproper && make menuconfig && \
make dep && make bzImage

selected 386 and several other options as you
can see in .config which can be obtained from
http://portal.promon.cz/ledvinka/i/tscerr/config

All changes were done entirely via menuconfig.
Result of booting up the kernel is:

CPU: 386
Kernel panic: Kernel compiled for Pentium+, requires TSC feature!
In idle task - not syncing

So i guess i just have to comment out
CONFIG_X86_TSC
that will be my first try.

Do not i have switch it for:
CONFIG_X86_TSC_DISABLE
Sounds like it is option for kernel
not to use TSC although it's present?

Please CC me. Words comment out OR switch should be enough ;-)
