I have a PI 4 (4GB)
I loaded and installed the arm64 eoan
USB didn't work, ssh did
I set total_mem=1024
USB worked
I set total_mem=3072
USB failed
I set total_mem=1024 and loaded the linux image:
wget
https://people.canonical.com/~hwang4/rpiv2/arm64/linux-image-5.3.0-1008-raspi2_5.3.0-1008.9+newupdate_arm64.deb
wget
https://people.canonical.com/~hwang4/rpiv2/arm64/linux-modules-5.3.0-1008-raspi2_5.3.0-1008.9+newupdate_arm64.deb
sudo dpkg -i linux-modules-5.3.0-1008-raspi2_5.3.0-1008.9+newupdate_arm64.deb
sudo dpkg -i linux-image-5.3.0-1008-raspi2_5.3.0-1008.9+newupdate_arm64.deb
sudo reboot
USB Worked
I commented out the total_mem=3072
USB failed
I believe the following will help:
In the raspberry pi git (4.19.y)

"I've created a trivial patch to add bounce buffers on ARM64 for
pcie-bcrmstb.
pcie-brcmstb-bounce64.patch.zip
I tried this patch, it works for me!
All 4G memory is alive now, COOL !! :-)
Thanks @yaroslavros !

fixes yours
