log

I am observing repeated Intel ISH driver errors on a Lenovo ThinkPad X9-14 Gen
1
with an Intel Lunar Lake CPU running Arch Linux.

# System information

Kernel: 6.19.6-arch1-1
Distribution: Arch Linux
Laptop model: Lenovo ThinkPad X9-14 Gen 1 (21QBS0KV00)
CPU: Intel Core Ultra 7 268V (Lunar Lake)
Architecture: x86_64

# Hardware

lspci:

00:12.0 Serial controller [0700]: Intel Corporation Lunar Lake-M Integrated
Sensor Hub [8086:a845] (rev 10)

# Kernel messages

The following messages appear repeatedly during boot:

intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10
intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10
intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10

# Kernel modules

lsmod | grep ish:

intel_ish_ipc          32768  0
intel_ishtp            86016  1 intel_ish_ipc

# Observations

The system uses the Lunar Lake integrated sensor hub (ISH). The driver
appears to attempt to load firmware but reports repeated "cmd 2 failed 10"
errors.

It is unclear whether:

- the required firmware is missing,
- the device requires new kernel support, or
- this message is expected for unsupported ISH features.

# Attachments

I have attached the following logs:
- full dmesg
- lscpu
- lsmod
- acpidump

Please let me know if additional information would help diagnose the issue.
