Coral TPU pcie/M.2 issues on Debian 12 0 - AMD am4 build

[dmandn]

Description

Hi, I'm on Debian 12, tried with a kernel 6.8 install, plus proxmox 8 with kernel 6.8.x and now I'm on Debian 12 again (another fresh install), on kernal 6.1.0-21-amd64. I have followed your steps to build and install this version of gasket-dkms and from the basic checks, things seem ok on the host, but I cannot get the TPUs to work in/with anything.

When I perform a "dmesg | grep -i apex", I get the below:

dmesg | grep -i apex

I have the same symptoms with this gasket-dkms build as I had with a previous one, except the permission denied errors are gone from the dmesg output now. Still unable to clear the "Couldn't initialise interrupts: -22" error, which I assume is part of the issue? Any help would be greatly appreciated as I have been fighting with these Coral TPUs for 1 week now.

...Also please advise if this is the wrong place to ask and I will move my post to wherever can be suggested.

Hi,

I solved similar issue by doing this :

echo 1 > /sys/bus/pci/devices/0000:08:00.0/remove
echo 1 > /sys/bus/pci/rescan
