[SOLVED] Intel ISH problems on Panther Lake

eternalflameiv · 2026-03-08 23:26:09

My laptop (a Panther Lake MSI Prestige Flip) is supposed to have accelerometers for 2-in-1 usage, but it seems that the sensor hub for the accelerometer is down. I see this in the dmesg:

[   15.861452] intel_ish_ipc 0000:00:12.0: ISH loader: load firmware: intel/ish/ish_ptl.bin
[   15.870981] intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10
[   15.878639] intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10
[   15.886478] intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10

Similar errors reported elsewhere usually are blamed on vendor-specific firmwares or other incompatibilities that stop the existing firmware from working with the hardware.
According to the Linux Firmware git, the included firmware (link to relevant linux-firmware git commit) is version 5.8.1.7778, while Windows Device Manager reports that the firmware for the sensor hub is version 5.8.56.0 (link to relevant update in the Windows Update Catalog). As far as I can tell, this is an unmodified firmware version from Intel distributed via Windows Update, so there aren't any driver install packages that I can extract the firmware from. Does anybody know how I'd be able to get the firmware or report the problem upstream?

Error matches https://www.spinics.net/lists/linux-input/msg96611.html but idk whether MSI also needs/provides custom FW

MSI does not provide any custom firmware installers, or I would have tried to rip firmware images out of them already

As far as I can tell, according to Windows (where the sensors work) these drivers came from a Windows Update package directly from Intel. I have no clue whether this implies that the package is altered by MSI or not and also don't know how anybody would go about getting those firmware images.

Brief google survey suggests that MSI very much provides an "IshHeciExtension" driver - what exactly is your device?
https://gitlab.com/kernel-firmware/linu … 71f96ee2e5 is from 10/11/25 while https://www.catalog.update.microsoft.co … 6a544a88bb is from 10/20/25 so iff intel really has bumped the driver within that week you'd have to contact them about updating the firmware provided to linux, otherwise MSI would have to upstream their firmware (afaict Samsung however never did for the LL device…)

It turns out that I wasn't smart enough to go to MSI's support page and look for a driver package, which definitely is there. There are some raw firmware images inside; I managed to get one of them to load just by replacing the file inside /usr/lib/firmware/intel/ish. (The working version is in fact 5.8.1.7779 - above the one in linux-firmware. The firmware blob is about half the size of the one in mainline linux-firmware. I don't know how to tell or if I can tell if this was a vendor modification.)

Do you still run into the loader error?
Does the gyro now work?

eternalflameiv · 2026-03-22 18:09:34

No loader errors; gyroscope now working. I'm just wondering if I should take this to Intel and see if there really was a firmware bump or if this is a MSI custom version.

You could ask MSI whether this has been upstreamed to intel - "about half the size of the one in mainline linux-firmware" doesn't sound like it's the generic one.
You can also record this at https://wiki.archlinux.org/title/Laptop/MSI for other MSI owners.

And please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
