This is a problem with cmov instruction. I have processors without this instruction.
I think, intel was removed for later processors.
Now, I have problems for boot with kernel panic.
I like compile for 586 or 486. I think this is a very good option.February 2, 2009 at 10:29 pm #47541
What processor has this problem?February 3, 2009 at 12:05 am #47542
What processor has this problem?
But, if you compile for pentium, 586, pmmx I dont have problems.
My other problem is when I boot with your precompiled kernel changin only target processor option. I have this message:
Probing [hda] IDE device to startup the system …
Loading root filesystem into RAM device… Success
loop: module loaded
VFS: Cannot open root device “” or unknown-block(8,2)

How it is ?February 3, 2009 at 10:38 pm #47543
Have you updated the initrd with the kernel modules that you compiled?
I think that that is the issue.

I’m experencing a kernel panic errorr too
because my processor is missing the cmov instruction.
Processor Type is “VIA Samuel 2”
Which is the best way to solve this issue ?
ThanksMay 1, 2009 at 7:40 pm #47545
Is there a solution for this yet? I also have a device with a processor that does not support the cmov instruction. 😥July 12, 2009 at 7:45 am #47546
I’m not sure whether my problem depends on cmov or something else, but it happens on several old pc’s: a 120 MHz Pentium, a 500 MHz K6-2, …
The kernel seems to boot ok, but when it should start init, nothing happens. The last message, in verbose mode, tells about freeing 260k kernel memory.
The requirement for the processor is 233 Mhz. Why? Does it really mean Pentium II?
The versions 1.0.beta9 and 1.0.beta12 behave like this, 10.0.beta11 (on the 120 Mhz Pentium) complains about some missing processor feature and stops earlier.
How do I compile own kernel and build an iso image?
