Hi Aaron,
I did:
$ sudo dpkg -i linux-{ image,headers} -4.20.0- rc3+_4. 20.0-rc3+ -6_amd64. deb
# edit /etc/default/grub so it now reads: LINUX_DEFAULT= "acpi_osi= ! acpi_osi='Windows 2009' modprobe. blacklist= nouveau rmi_core. debug_flags= 0x7"
GRUB_CMDLINE_
$ sudo update-grub
$ sudo /sbin/shutdown now
# reboot into kernel 4.20
# touchpad now more responsive - it picks up lighter and faster touches as clicks.
# close lid to suspend. on first two wakeups, touchpad worked
# on third wakeup, touchpad didn't work. then:
$ cat /proc/interrupts | grep rmi > rmi_irq.log
# move finger around on touchpad for several seconds, even though mouse pointer didn't move
$ cat /proc/interrupts | grep rmi >> rmi_irq.log
# rmi_irq.log is empty
$ journalctl -b 0 -k > journalctl.log
# just for curiosity, close lid again, wait 10 seconds, reopen. Still, mousepad is unresponsive.

$ journalctl -b 0 -k > journalctl. after_blink. log
$ wc -l journalctl.* after_blink. log
1735 journalctl.
1586 journalctl.log
Have attached journalctl. after_blink. log
Thanks in advance for any information you could provide!
