Well, the ASM chip in it is listed in the kernel's built in blacklist. So, I would say no, but it seems to work without the uas driver. The underlying cause seems to be my USB 3 cards themselves. They use a Renasas uPD720200 chip, which I have been unable to update the firmware through Linux, Dos, or Windows. Unfortunately both of the machines in question had this card installed. I did however find a USB 3 card with a Renasas uPD720202 chip in my pile of expansion cards and both bridges appear to work even if on the kernel blacklist. So all of this stuff goes in the 'iffy' pile of hardware. I am not willing to trust it or a manufacturer whose definition of compatible is that the computer doesn't go up in flames when used. Tape is slow, but my hardware has never complained about working the midnight shift and tape has always been reliable for me.

Well, I haven't measured, but it seems fast. Maybe I should reach for iotop next time I have that drive connected. I would expect the drive rather than the interface to be the limiting factor. ael ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

[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. kdibble@anna:~$ apt list coreutils Listing... Done coreutils/stable,now 8.32-4+b1 amd64 [installed] kdibble@anna:~$ uname -a Linux anna 5.10.0-9-amd64 #1 SMP Debian 5.10.70-1 (2021-09-30) x86_64 GNU/Linux kdibble@anna:~$ cat /etc/issue Devuan GNU/Linux 4 \n \l kdibble@anna:~$ df df: /run/user/1000/doc: Operation not permitted Filesystem 1K-blocks Used Available Use% Mounted on udev 6094116 0 6094116 0% /dev tmpfs 1224600 1060 1223540 1% /run /dev/sda1 114792580 5642064 103273168 6% / tmpfs 5120 4 5116 1% /run/lock tmpfs 4965560 0 4965560 0% /dev/shm /dev/sdb6 239709796 53920084 173540320 24% /home tmpfs 1224596 12 1224584 1% /run/user/1000 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. Thanks.
