Description of problem:
On my dell Insprion 4150 the onboard pointing device is a synaptics
touchpad/point stick combo. While trying to get the latest test kernel happy, I
discovered that the (new?) synaptics driver doesn't like APM - suspending the
machine produces a message about failing to attach the driver, and on resume,
any touch of the pad produces "lost sync at packet 0" messages.
(Yes, I know ACPI is the "one true way" for power management - only problem is
it doesn't work on any hardware I've encountered - which makes it rather
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot the kernel with acpi disabled (acpi=off)
2. suspend the machine
3. resume the machine
I get the same error since around the same kernel from Arjan whenever
I boot that kernel. I'm pretty sure it was introduced around that
version. It was working with .4x.
fixed in current kernels ?
I no longer have the hardware I observed this bug on - so I can't say.
