What you're seeing is a tripple fault. I don't know why this is happening, but usually it has something to do with the double-fault mechanism being damaged (or not set-up) when a double-fault occurs. You mentiuon 386 - I rememeber in OS/2 we have many work-arounds for Intel processor errata - it might be possible that Linux hasn't catered for all the I32 386 errata - some of these errata apply to memory management and that's significant since a tripple fault is often caused by either stack faults or descriptor faults - both memory problems (I am assuming without checking the Linux uses a task switch for a double-fault, if it doesn't then a simple double-fault caused by a stack exception in ring 0 will result ina tripple fault.).
Again, if this is a 386 issue then you should be aware of the increased instrcution set for 486, 586 etc..

I'm trying to get a linux-2.4.0-test9-pre7 kernel with riel's recent memory swap patch going on a 386 - swapping problems with the 2.2.15 kernel I was using prompted this.
I'm trying to make it run on a bull netstation, which means using bootp and etherboot tagged kernels.
When I compile using gcc version 2.95.2, the resultant kernel reboots the machine each time its starts up - it does not get started. When I compile using gcc2.7.2.3, the machine just halts, with "Ok, booting the kernel" staying on the screen.
I am not on the kernel list, so please send me any replies.
I have not at this stage tried to see if any non patched versions of the kernel will work, nor have I tried to see if the kernel boots on my Pentium Pro (but could do so with some prompting).
Regards,
