Subject: [DNG] Chimaera Oddities
A couple of oddities.

The uas driver does not like the JMicron Sata/USB 3 bridge.

Bus 004 Device 003: ID 152d:0578 JMicron Technology Corp. / JMicron USA
Technology Corp. JMS567 SATA 6Gb/s bridge

I blacklisted the the device as follows and all seems to work as expected.

cat /etc/modprobe.d/blacklist_uas.conf

options usb-storage quirks=174c:5136

There seems to be a problem with df.  I have three machines running
chimaera andthe oddity only happens  on one.

There also seems to be a problem with the grub graphical display on the

machine with /boot on a disk and / on a pci nvme card. Still trying to run

down the details. Forcing it to a non graphical display makes the errors
go away

the machine boots  either way, so it hasn't been a priority.
