Somehow I feel there is a bug in update-initramfs.
So after install custom blobs:
$ ls -l|awk '/->/ {print $9 " " $10 " " $11}'
ish_lnlm_39ceeaf8_0f095bd1.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm_39ceeaf8_27e280ea.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm_39ceeaf8_2d924439.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm_39ceeaf8_46171bac.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm_39ceeaf8_793c79e4.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm_39ceeaf8_916dce72.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm_39ceeaf8_af74be99.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm_39ceeaf8.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm_39ceeaf8_d8738e0f.bin.zst -> ish_lnlm_39ceeaf8_58.7724.2.bin.zst
ish_lnlm.bin.zst
The custom blob is not loaded unless one symlink it as the default
ish_lnlm.bin.zst:
[ 1.508997] intel_ish_ipc 0000:00:12.0: ISH loader: load firmware:
intel/ish/ish_lnlm.bin
[ 1.534957] intel_ish_ipc 0000:00:12.0: ISH loader: firmware loaded.

[ 1.534959] intel_ish_ipc 0000:00:12.0: ISH loader: FW base version:

[ 1.534961] intel_ish_ipc 0000:00:12.0: ISH loader: FW project version:
58.7724.2.12658
And from update-initramefs messages, custom blobs are not included into
initramfs and therefore not detected:
$ update-initramefs -v -u -k $(uname -r)
...
dracut-install: Missing firmware intel/ish/ish_*.bin for kernel module
