Cyrix Cx486DRx2-16/32 CPU causes kernel to panic

Post by Michael A. Sta » Sun, 27 Nov 1994 17:53:53


has/does anyone have a Cyrix "clocked doubled upgrade processor" running
lynix? Mine panics in a repeatable fashion with a "gerenal protection"
error. i have the entire message if anyone is interested.



1. Kernel panic with Cyrix Cx486 S25 CPU (similar to U5 CPU panic)

He resolved his problem by installing an Intel CPU.

I have a Cyrix Cx486 S25 FasCache (Cx486S-25GP) processor that fails in
the same way.  The messages are:
   math_emulate: 0010:0010ebb4
   Kernel panic: Math emulation required in kernel
   In swapper task - not syncing

The kernel should have math emulation support.  It's the same kernel that
I use on a AMD 386SX/25.  I've also tried the boot/root image diskettes--
similar results.  I'm running Linux 1.0.8.

Any ideas?  TIA.

2. kernel mode physical memory allocaion

3. TLS566 -- 16 bit samples cause kernel panic

4. Adaptec 2940 support?

5. Calling 16-bit PM code from 32-bit PM Kernel Driver

6. HW platform != x86 wanted. Any idea?

7. RH 5 (2.0.32) crashes on Cyrix 6x86 - kernel workaround?

8. routed and route source code

9. PCNet 32 Kernel Panic

10. kernel panic in 2.0.32

11. Cyrix Cx486DRx2

12. Does Linux Run on a Cyrix Cx486DRx2

13. Cyrix 386 upgrade : Cx486DRx2
