Hello,
There is an issue with the identification of ATA drives with our
P.A. Semi Nemo boards [1] after the
commit "of/irq: Factor out parsing of interrupt-map parent
phandle+args from of_irq_parse_raw()" [2].
Error messages:
ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4)
ata2.00: qc timeout after 10000 mssecs (cmd 0xec)
Screenshots [3]
I bisected yesterday [4] and "of/irq: Factor out parsing of
interrupt-map parent phandle+args from of_irq_parse_raw()" [2] is the
first bad commit.
Then I created a patch for reverting this first bad commit. I also
reverted the changes in drivers/of/property.c. [5]
The patched kernel boots with successful detection of the ATA devices.
Please check the of/irq updates.
It is hard to understand what is going on with so little information.
Please provide the device tree for your platform. It isn't possible to
debug this without it, no matter how many pictures you provide. If it
doesn't exist in source form, you can dump it using:
# dtc -I dtb /sys/firmware/fdt
and posting the full output.
Additionally, a full dmesg of both working and non working boots would
be useful.
Thanks,
M.
