dmesg when suspending with sbs being unloaded
On my Acer Travelmate 4002 WLMI, the sbs (Smart Battery Subsystem) module is
causing the kernel to lockup when suspending or shutting down.
The system then becomes unresponsive and requires a power cycle to reboot.
This does not happen when the sbs module is unloaded prior to suspend/shutdown,
however using "modprobe -r sbs" causes a kernel oops. So both the sbs and the
sbshc modules need to be unloaded manually using "rmmod <module>".
If the kernel oops occured, the system also fails to suspend/shutdown.
This issue is also present when using a 5.10 series kernel, and likely also
when using a 4.19 series kernel.
