I have updated from the latest stable version to 6.10.0-rc2 and after reboot severe issues started to appear. Cache pool disks were unmountable and I couldn't manage to successfully restore data (tried with command "btrfs restore -vi" as suggested in thread Faq for unRAID V6). I then reformatted pool disks and restored docker files, but it didn't help. I am getting all kinds of errors like BTRFS error (device loop2), Call Trace errors and my /var/log is getting full. One of the disk arrays also started reporting file system errors. Attached please find the diagnostics file. Do you have any idea what is wrong?

Added for Unraid 6.7
Thank you very much!

Several requests have already been made on the forum (Link 1 and Link 2) to add support for CH340 USB to TTL converter. I have already sent a request also to Limetech, but haven't received any feedback yet. Enabling the driver that should be present in the kernel, would allow the use of cheap arduino boards for home automation purposes.

I am also having issues with Arduino mega 2560 driver in unRAID. I can't load ch341 module.
root@unRAID:~# modprobe ch341 modprobe: FATAL: Module ch341 not found in directory /lib/modules/4.14.13-unRAIDAny ideas what else to try?
-
Anyone here with CH340 chip properly assigned and working on unRAID?
I have replaced USB cable and tried with USB 2.0 port but it doesn't help. On the other hand Arduino is detected properly under Windows. Do you have any idea what else to try?

Another request to add extra drivers. For home automation (RF Link gateway) I use Arduino Mega 2560 with CH340G USB to TTL converter. When I connect it to unRAID 6.4.0_rc21b Arduino is recognized as:
Bus 004 Device 002: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
I want to pass it through to Domoticz container but setting extra paramerer as ''--device=/dev/bus/usb/004/002'' doesn't work. I suspect it is due to lack of CH340G driver in unRAID as device doesn't get assigned as TTYUSB. Am I missing something here?
Is there any chance to include CH340 driver to unRAID so it could be more for appropriate as a base OS for DIY home automation projects?

I want to use an existing topic as I am also getting Call Traces errors. Attached you can find diagnostic files.
From the system log I can see errors like this:
python[12239]: segfault at 2aadb4b2dff8 ip 00002aadb00d96d1 sp 00002aadb4b2e000 error 6 in libpython2.7.so.1.0[2aadb006b000+342000]
and call trace like this

Do you have any idea what is causing the errors?
unRAID crashing after update to 6.10.0-rc2

Thank you very much for the helpful feedback. It is a great community.
I ended up with a corrupted array and an unmountable pool. Luckily I have managed to complete xfs repair on the corrupted array drive and restored pool data from a backup.
