Hello,
The Nemo board [1] doesn't recognize any ATA disks with the
pci-v5.16 updates [2].
Error messages:
ata4.00: gc timeout cmd 0xec
ata4.00: failed to IDENTIFY (I/O error, error_mask=0x4)
ata1.00: gc timeout cmd 0xec

I was able to revert the new pci-v5.16 updates [2]. After a new
compiling, the kernel recognize all ATA disks correctly.
Could you please check the pci-v5.16 updates [2]?
Please find attached the kernel config.
Thanks,
Christian

Hi All,
Many thanks for your nice responses.
I bisected today [1]. 0412841812265734c306ba5ef8088bcb64d5d3bd
(of/irq: Allow matching of an interrupt-map local to an interrupt
controller) [2] is the first bad commit.
Can you please give the following hack a go and post the result
(including the full dmesg)?
Thanks,
M.

The detecting of the ATA disks works with this patch! Well done!
Thanks a lot!
Thanks for testing it. I'll turn that into a proper patch.
M.
Could you please explain your patch?
Please refer to the commit message[1].
I am not a developer. I work for the A-EON Linux FLS.
I have no idea what this is, unfortunately.

I have to explain our customers why the kernel doesn't detect their
ATA disks anymore. :-D But it is fixed and I don't need to explain it.
Thanks a lot for your help.
