I'm having exact the same issue, also on Unraid 7.2.3 (Samba version 4.23.4) and Tahoe 26.2. I have also tested new backup from scratch, tried creating brand new share as well. No Luck. I see a following line item on macOS logs though. I have manually tested the permissions and they are setup correctly, I can read and write to the share. 2025-12-20 17:22:04.394086+0000 localhost SystemUIServer[8090]: (TimeMachine) [com.apple.TimeMachine:TMDisk] attrVolumeWithMountPoint 'file:///Volumes/.timemachine/Tower._smb._tcp.local/XXX-404A-4AC8-9720-XXXXXX/timemachine/' failed, error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied"

Thanks for the help, running memtest was a good shout, It produced errors within first 5 minutes. The only thing I could think was either a bad ram or XMP profile which I disabled and ran the full test again and all the tests passed without XMP so that's what I'm going with for now. Once again, appreciate your help.

Right, so still having the same issue. I have turned syslog and notice the following 1. Several AER errors. I have tried fixing them with adding the pcie_aspm=off flag to the sysconf file. The errors are gone but I'm not sure if this flag has actually solved the issue or just suppressed the errors ?

This could be due to illegal access to memory ? I'm not too sure about this one. I will add the following flag (pci=nommconfto) to see if this solve these errors.

All of this makes think I might be having hardware issues ? loose connection somewhere maybe ?

Thanks for the help, the network protocol is already set to IPv4 only, unless there is another option somewhere that I'm missing? I have moved up to v6.12.3-rc2 and also enabled syslog. I will test further and report back.

Hi Folks, I'm scratching my head with this one. Every few hours I lose complete network connection and the systems needs a force restart to fix the issue. I have not made any hardware changes and don't really recall if it started happening after updating to 6.12.2 or before. Any help will be much appreciated.

Just an update, it's been fixed after a week of trying everything. The solution turned out to be completing shutting down the server and unplugging it from the power. A simple restart won't do anything. The idea came from the following post where it is mentioned at the end that the author of that post had to do same thing.

I have also tried the following in the config pcie_acs_override=downstream,multifunction vfio-pci-ids=8086:a2af,8086:a2ba,8086:a2c5,8086:a2a1,8086:a2f0,8086:a2a3,10de:1b06,10de:10ef,168c:003e,1b21:2142 modprobe.blacklist=i2c_i801,i2c_smbus but still no luck. Would really appreciate if someone is willing to help.

Hi Folks. hoping that someone would be able to help me out with audio issues, When passing through onboard audio from an Asus motherboard to windows 10 VM. The sound was working fine and then suddenly after a windows reboot it disappeared. Under the device manager I get the following error when looking into the driver: This device cannot start. (code 10) My initial thought was that it could be due to RC version of Unraid so restored it to a stable version and issue remains. So far I have tried reinstalling drivers, reinstalled windows OS, also tried passing audio to a Linux VM without any luck.
