My laptop already has /sys/power/mem_sleep as "deep" and it still hangs when I

The "deep" mem_sleep approach works for me. I also downgraded to
vanialla 19.10 kernel before trying this. Not sure if it also works with
5.4 kernel. Will try this weekend.
Earlier I was making a mistake in writing "deep" into mem_sleep. Just
sudo echo deep > /sys/power/mem_sleep does no
Reporting after a long time, but the s2idle=deep does not really fix anything.
Just made it less frequent if at all. Since then I have upgraded to 20.04 and
the issue is there.
I have essentially given up on using any kind of power management on this
laptop under Ubuntu.

Ok. Tried the latest kernel I could find in mainline
user@user-305U1A:~$ uname -a
Linux kedar-305U1A 3.4.0-030400rc6-generic #201205061835 SMP Sun May 6 22:36:08
UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Still the same problem. No improvement.

I would try out the BRCM STA drivers when I get access to the laptop and
report.
But the GPLed BRCM driver should work with this hardware w/o needing
anything special like the STA driver.

No luck with the wifi on this laptop with any linux flavour yet.
http://www.linlap.com/wiki/samsung+305u seems to indicate this is a wifi driver
bug in brcmsmac that does not affect the brcm-wl.
I have no trouble with the wifi in Windows. I am reluctant to open the
laptop.
