The 2-in-1 keyboard/touchpad disable at 180 degrees works, but that is handled outside the ISH. Kernel: 7.2.12 (Fedora 44), linux-firmware 20261019, BIOS Insyde F.20 (04/27/2026, latest available from the vendor). DMI: sys_vendor = HP product_name = HP OmniBook X Flip Laptop 14-fm0xxx product_family = 103C_5335M8 HP OmniBook X product_sku = B5UJ1UA#ABA dmesg: intel_ish_ipc 0000:00:12.0: ISH loader: load firmware: intel/ish/ish_lnlm.bin intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10 (three times) >From drivers/hid/intel-ish-hid/ishtp/loader.h, command 2 is LOADER_CMD_START, so the query and fragment transfer steps succeed and the bootloader refuses to start the image. I have not been able to confirm what status 10 means. The vendor-specific lookup finds nothing for this machine. The CRC32 values are vendor(HP)=12128606, family=604fc7b4, name=e4cc03e5, sku=dc6e7f5f, and none of the ish_lnlm_* names built from them exist, so the generic ish_lnlm.bin is loaded. linux-firmware does carry an HP file, intel/ish/ish_lnlm_12128606_f9751b71.bin (5.8.200.7720_1029), but its second CRC matches neither this product name nor this SKU. A complete power-off (not a reboot) and a BIOS check did not change anything. Questions: 1. Does status 10 mean the bootloader rejected the image (signature or platform mismatch), and is the generic firmware expected to work on OEM-customised ISH platforms at all? 2. Is there a known HP firmware for this SKU/family, or is HP expected to submit one to linux-firmware? I can provide more logs or test patches on this hardware.
