Hi,
After removing my head from my a**, I revised the code that checks
the memory copy in the fast_page_copy routine. The machine then
proceeded
not to stop at my panic, but I got my "normal" oopses. I then had an
idea and removed all the prefetch instructions from the beginning of the
routine and tried the resultin kernel. I now have no crashes.
What could this mean?
Here is a nother patch just so you can keep me honest if I
made another mistake:
-------------------------
diff -r ./arch/i386/lib/mmx.c ../lin2/linux/arch/i386/lib/mmx.c
149,150c149
<
< /* __asm__ __volatile__ (
---
> __asm__ __volatile__ (
158c157
< "3: movw $0x1AEB, 1b\n"
---
> "3: movw $0x1AEB, 1b\n" /* jmp on 26 bytes */
166c165
< */
---
>
170c169
< "1: nop\n" /* prefetch 320(%0)\n" */
---
> "1: prefetch 320(%0)\n"
-------------------------
Please let me know if that makes sense :).
Thank you,
Seth
