hi,

are all of you really sure you are looking for this bug in the right
place?
I've got a good old P90 here running 2.1.120pre3 and
/proc/cpuinfo gives me (erroneously)

model : Pentium 75+
vendor_id : GenuineIntel
stepping : 1
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no

while I know this machine has a) the f00f and b) the fdiv bug.

On the other hand, the boot-sequence shows

<4>CPU0: Intel Pentium 75+ stepping 01
<5>SMP motherboard not detected. Using dummy APIC emulation.
<6>Checking 386/387 coupling... Hmm, FPU using exception 16 error
reporting with FDIV bug.
<6>Checking 'hlt' instruction... OK.
<6>Intel Pentium with F0 0F bug - workaround enabled.

so the problems are detected, measures taken and I won't worry :-)

I guess it's just the code that gives the values in /proc thats
buggy .... well, sorry but I'm missing the time for a closer look.

with kind regards,
