Hello everyone, any news? I'm facing the same problem. Couldn't reiinit interrupts: -524

@MappyMatty I've noticed the same issue after the kernel upgrade to 6.12.x. I have attempted the following:

• cloned the gasket repo
• changed the .llseek = no_llseek to .llseek = noop_llseek ( vide: https://github.com/lukaszraczylo/gasket-dkms )
• built and installed the package

But then kept getting Couldn't reinit interrupts: -524 all the time, so after few hours I decided to run the model interference on CPU until the solution is found 🤷‍♂️

Got same problem on latest raspberrypi os with latest kernel. But when i've downgraded the kernel to 6.6.74+rpt-rpi-v8 - got it working, thought have to reload apex driver and rescan bus.

I still have apex 0001.03.00.0: Couldn’t initialize interrupts: -524. I’m using a Pineboards HatDrive! AI with an NVMe drive as well as the Coral. Are others using this same board or other PCIe boards? Could this issue relate to the PCIe switch on the board? Struggling with this and close to giving up and exploring Hailo as an alternative…

Well, i was getting same messages (couldn't initialize interrupts: -28 without applying dtoverlay=pineboards-hat-ai and -524 when applied) on 6.12 kernel. But when downgraded kernel to 6.6.74+rpt-rpi-v8 - these errors gone. Only problem is that i have rmmod apex/remove pci-e device/rescan pci/load apex mod after boot to get coral working. I have 52pi PCIe hat M02.

I'm using a hat with two m2 slots from another brand but facing the same problem. Downgrading the kernel to a previous version worked just fine, I'll keep using it for now and never update if possible.
