SubjectBug in APIC on 2.4.20 kernel
From
Date
Hello,

I found a problem with the APIC management in the 2.4.20 kernel.

My system is (was) a bi-processor one :

MSI K7D Master (BIOS V 1.1) with 2 ATHLON MP 1800+

The facts :

1) The 2.4.20 kernel was OK on my system with the 2 processors and a
home made SMP kernel.

2) One processor was broken/defective.

3) No boot was possible with only on processor on the card with a loop
while booting saying endlessly : "APIC 04(04)"

I try to recompile the 2.4.20 kernel with no SMP support the problem was
the same, I try gcc2.95 and gcc3 without any success.

4) The system runs fine with a 2.2.22 home made kernel, the APIC works
well with my lonely processor ... (cf attachment dmesg.2.2.22).

As the system does not run with 2.4.20 kernel I made "ver_linux" under
the current (2.2.22) kernel (cf attachment ver_linux.txt).


Regards
