Another entry for the MCE-hang list

[Richard Gooch]

  Hi, all. I just booted 2.4.19-pre3, and it hung right after the MCE
message. This is an Asus P2B-D with two Intel 450 MHz PIII's. Output
of /proc/cpuinfo appended.

Won't that change hang on *all* pii/piii systems? (I've only tested it on
one pii box)

My ASUS P2B-D with dual P-II 400's is strange...

I -was- getting the hang, but then I recompiled on a different host, 
with possibly a different compiler, and the hang went away.  Sorry I 
cannot be more specific than this :(

The "running ok" case, which came -after- the hang case, was 
2.4.19-pre3-BK-latest with gcc 3.0.4-MDK.

I'm using egcs-1.1.2. I've bailed out of gcc-2.95.3 because it's
buggy.

egcs-1.1.2 is known to miscompile some driver code and other oddments in
2.4.

Oh, really?

| COMPILING the kernel:

|    also work but is not as safe, and *gcc 2.7.2.3 is no longer supported*.
|    Also remember to upgrade your binutils package (for as/ld/nm and company)

(2.4.18 linux/README)

linux/Documentation/Changes is more helpful, though.

See linux-kernel for the past week. Its been discussed repeatedly. Pre3 only
works on non intel chips unless you kill MCE support
