Hi Dmitry,

Sorry for the badly threaded reply, I wasn't subscribed to the list and
didn't ask explicitely to be Cc-ed.

By bad state I mean that neither touchpad nor keyboard are working. They
are both unresponsive. You can fix this by adding i8042.reset on the
kernel command line, or removing the battery and waiting long enough.
By very first boot I mean when the laptops are received from Dell and
booted in Linux.

If you cold boot with a working non-Dell power supply (with same
electrical characteristics), you can reproduce the "first boot" bug as
much as you want, and laptops won't work unless you remove the battery
and wait long enough OR add i8042.reset on the cmdline.

Regards,
