Hi..
I have MDK 8.2 and I get this error with: MDK 8.2, RH 7.2, RH 7.3.. but
just with ONE COMPUTER, the other computers works fine.
Ok.. I have a SpeedTouch, but to get it work I need to
1) modprobe the module
2) Then.. call the speedmgmt (a binary)
When I call the speedmgmt, I get:
Process speedmgmt (pid: 1748, stackpage=c1827000)

Why I get that error?
I have a Compaq (AMD K6 - 500mhz) and 64 of Memory.

Because you are trying to execute a CMOV (0f 4x) instruction. The module
you are loading is compiled for PPro or higher.

Hence no CMOV support (cat /proc/cpuinfo).

1) Whats that? the CMMOV?..
2) Could I fix it with the kernel?.. YES, how?. Please Im newbie and I would
like to fix it.
3) If the fix its in the kernel, at what menu is it?.
Thanks.

Ohh.. ok..
So.
1) Its more a HW problem? (a PRocessor problem?) I have AMD K6
2) So.. you are telling me that I cant solve it? :(, only if I change the
proccessor to a Pentium?..

it's an instruction, "conditional move", which appeared first
in the Intel P6, and is not supported by your processor.

no, it's not a kernel issue. the problem is the binary module
you are trying to use: whoever compiled it chose compiler flags
that make it impossible to use on your CPU (any CPU which lacks
cmov, such as all pentium's (P5), K6, etc. athlons, though,
have cmov.)

none. strictly a problem with the module.

It's a problem with the module code. It should be sufficient to replace
cmov with something that can execute on < P6. That means, hand-checking,
depending on !CONFIG_MPENTIUM4.

There has also been a patch on L-K which implments CMOV on prior-PPro

It seems that you have to recompile the module for yor processor, or if
you want you can use the cmov emulation (and others) patch that has benn
submited a few days ago by Willy Tarreau.

It has a hideous overhead. Just dont use cmov blindly in kernels. The kernel
stuff will take care not to let the compiler stick cmov instructions into
a non ppro+ kernel

The module you have is faulty. Get the open source replacement stuff for the alcatel
code and it might actually work

Not only nasty overhead but potential nasty implications. You get
exception where you'd normaly get simple instruction. Do NOT use cmov
emulation for kernel.
