November 7, 2025Nov 7 I just ran the 7.2 update on this machine and everything went file until the reboot step, then I got this.Does this mean the flash drive is buggered? I have backup of the flash drive made just before I did the upgrade, but I would like to move to 7.2 if possible.thanks!
November 7, 2025Nov 7 Community Expert It could be worth downloading the zip file for the release and then extract all the bz* type files overwriting those in the root of the flash drive. For some reason it can help if the system is having trouble reading these reliably from the flash drive.Having said that there have bern reports of the 7.2 release having problems on Macs (a suspected kernel compatibility) so if that does not work then reverting to the backed up release might be best.
November 7, 2025Nov 7 Author Thanks for that. I will download the current release and copy over the bz* file and then should I run the make bootable script?

November 8, 2025Nov 8 Community Expert Try booting with a new flash drive using a stock 7.2.0 install, no key needed, to see if it's a kernel compatibility issue with your hardware. Also, please post the main hardware used.
November 8, 2025Nov 8 Author I have down-graded to 7.1.3 by copying the bz.* files back to the usb from my back up and everything works as it did before.This is 2012 Mac mini.Does this signal a kernel issue? This is what ChatGPT thinks:It’s almost certainly due to a USB/xHCI initialization regression introduced in Linux 6.10.x — not Unraid-specific code.When enough users report it (and they will — Mac minis, older NUCs, and small-form Intel boards are common Unraid hosts), the Unraid team typically:Either backports the older USB driver behavior, orAdds a boot-time workaround (kernel parameter, delay, or firmware quirk).So once the kernel maintainers fix it upstream, Unraid will inherit the fix.

November 13, 2025Nov 13 Community Expert Solution Yes, but best bet for now is to remain on 7.1 and wait for 7.3, then retest there.
