SubjectPROBLEM: smp-system will work very slow with kernel 2.2.2
[1.] My smp-system will work very slow with kernel 2.2.2

[2.] After compiling the kernel 2.2.2 my system will work very slow. I
tried it with different settings, but the system will not
work right. With the old kernel. 2.0.36 everything works perfect (SMP,
too). With windows NT, SMP works, too.
I'm wondering why the bogomips of the second CPU is only 2.5. If I compile
the kernel for only one cpu the system will be slow, too. I don't know
what I do wrong. It's not the first kernel which i compile. I did it for
many systems but I had never so much problems. Ihe features, I used were
the same as the old one. I convertefd it with make oldconfig. As this worked
not fine, I configured a new kernel. This worked not fine too, so I use the
default features of make menuconfig. The only thing, I turned on was the Adaptec SCSI.
My board is a GA-686DLX, Distribution: SuSe 6.0.

[3.] speed, SMP, problem, kernel 2.2.2, compiling

[4.] Linux version 2.2.2 (root@Platos) (gcc version egcs-2.91.60 19981201
(egcs-1.1.1 release)) #8 SMP Fri Feb 26
16:00:22 CET 1999

[5.] no opps msg

[6.] no shell script is necessary to see how slow the machine works. You
can see how the computer will draw each line of
"make menuconfig" of the kernel src.

[7.3] no modules are installed. The kernel works with only the important
parts which are compiled inside the kernel.

I hope you will help me because I hate Windows NT and will change my
