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

ata3.00: gc timeout cmd 0xec
ata3.00: failed to IDENTIFY (I/O error, error_mask=0x4)

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,

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.
