Public bug reported:
Binary package hint: linux-source-2.6.31
When resuming from hibernate on Arrandale CPUs, the restoring of the
kernel image causes an oops. This always seems to occur on the final 4K
of a 4M boundary, such as at address 0xc03ff000. The oops can be
worked around by using kernel parameter "mem=nopentium" to stop using
mixed 4M/4K pages or disabling the kernel from being restored into 4M
pages (just force the use of 4K pages). The oops occurs in the
following code:
00000043 <copy_loop>:
43: 85 d2 test %edx,%edx
45: 74 11 je 58 <done>
47: 8b 32 mov (%edx),%esi
49: 8b 7a 04 mov 0x4(%edx),%edi
4c: b9 00 04 00 00 mov $0x400,%ecx
51: f3 a5 rep movsl %ds:(%esi),%es:(%edi) <---- oopsing here
53: 8b 52 08 mov 0x8(%edx),%edx
56: eb eb jmp 43 <copy_loop>
This can also be fixed by an appropriate TLB flush.
