I tried IPFire nightly build ISO, the loongson machine could not start from the ISO because the BIOS is not updated according to Loongson community. I don't know if anyone else has tried the nightly ISO on a Loongson machine with updated BIOS. > It was definitely able to detect the disk and complete the installation. What branch are you building against? Can you confirm that the system has successfully detected all disks? > the loongfire repo is clone of IPFire core190 when I started to port to loongarch64 with updated kernel 7.1.1 and many other addon customization, I manually started to sync loongfire repo from IPFire till core205 so the IPFire core installer code has never being changed. There are many variable factors here in the loongfire repo, but I am sure now that it is only glibc 2.43 to 2.44 update change triggering this issue, I have started to bisect process from 2.43 to 2.44, hopefully I can pinpoint the commit in glibc that triggers this behavior change. > -Michael > >> On 23 Oct 2026, at 03:23, Vincent Li wrote: >> >> Hi Michael, >> >> I mirrored your core205 toochain upgrade including glibc 2.43 to 2.44 update to the loongfire repo which is fork of ipfire on loongarch64. I noticed I could not install the ISO on loongarch machine after glibc update, if I only revert glibc 2.44 back to 2.43 in the toolchain, no installation issue. I assume IPFire loongarch port would have same issue since the loongfire fork has exact same installer code as IPFire.
