#FML 😭 The Qubes installer hangs during boot when IOMMU is enabled, and boots fine with it disabled but then the installer tells me that Qubes won't work right without IOMMU turned on (and understandably so).

Obviously I want it enabled, even if Qubes could work in a degraded state without it.

I feel like I got a raw deal here. I checked the HCL and picked out a motherboard specifically based on what was reported to work, and yet... In the past, I've bought motherboards which weren't on the HCL and they worked out better than this.

So next I get to see if there are any updates for my BIOS and try the Qubes 4.2 installer (I already had 4.1 on hand, do I tried that first). After that it'll be time to hit up the forums, I suppose.

Had the latest stable BIOS, updated to one labeled "beta" and got the same results.

Found someone else who ran into IOMMU causing the installer to hang and theonly suggestion was to use a newer version of the installer (e.g. a nightly build). No indication whether it worked or not.

Next up: the Qubes 4.2 installer

Oh fun! Been in a similiar issue yesterday - the weirdest error ever and no trace of where it actually comes from. Amazing stuff...

Good luck dude! I ended up flattening my whole homeserver after yeeting libc into high heavens. xD

Wow, libc. The only times I remember that causing me trouble is when writing exploits, and I can totally understand wanting to yeet it. 🤣

opkg remove --force(blablabla) libc

YEEEEEEEEEEEEEEEEEET xD

I somehow had libc++ and libstdc++ fighting over linkage priority whilst libc (musl) just did NOT want to be nice.

So... yeah. I haven't slept for 24+ hours; my night was a goner. xD

And the Qubes 4.2 installer booted just fine. I guess that forum post was onto something there.

My last ditch attempt to get my previous SSD to boot with the new motherboard has failed.

I thought maybe if I did a fresh install to a fresh SSD, it'd set up the UEFI variables in the BIOS to allow me swap the old SSD in there and boot up.

No such luck. So now I'm finally going to resort to restoring from a backup and then copying over the files that I manually rescued.
