Public bug reported:
hibernate.sh dies upon resume due to "scheduling while atomic", causing
a variety of problems (e.g., network drivers stay unloaded). See bug
59077 for details. It appears that the use of a 3DNOW-based memcpy in
the suspend code causes preempt_count to be improperly incremented. All
K7-based hardware is affected since CONFIG_X86_USE_3DNOW is on even for
386 kernels. This problem was found a few months back and fixed in
2.6.18. The patch commit message is attached.
Can this patch be applied in a Dapper kernel update? K7-based laptops
cannot hibernate successfully without it.
** Affects: linux-source-2.6.15 (Ubuntu)
