The above patch fixes the issue for me (on 32-bit mipsel), but would need some
further testing.
I wrote:

but I realized this has been broken by
commit 919af8b96c89 ("MIPS: Make definitions of MI

binary. In this case, MIPSInst_FMA_FFMT(ir) must be equal to 0x7, which
does not match that case label.
This causes emulation failure for the prefx instruction. Fix it.

More than anything, I suspect
Hello,
I also hit this bug on 32-bit mipsel, on the Malta platform in QEMU.
I used images from
https://ftp.debian.org/debian/dists/Debian12.8/main/installer-mipsel/current/images/malta/netboot/
Command line:
qemu-system-mipsel -cpu 24Kc -M malta -m 512
-kerne
