Please remember everyone this is an alpha release and should be removed after testing and providing feedback.
Do not use as if it is a final release.
Sure. Nevertheless I run 25.a1 for testing purposes as daily driver these days. Yes, I know what I’m doing. I have the 23.1 USB stick right next to me in the drawer, but never needed it. This is a pretty stable alpha 🙂 Many thanks @anticapitalista!
Here some good news: Some of the dmesg messages are not related to the 25 release:
From 23.1 dmesg after fully upgraded (2025-06-28)
[ 0.093299] DMAR: Host address width 36
[ 0.093301] DMAR: DRHD base: 0x000000fed90000 flags: 0x0
[ 0.093307] DMAR: dmar0: reg_base_addr fed90000 ver 1:0 cap c9008020e30272 ecap 1000
[ 0.093309] DMAR: DRHD base: 0x000000fed93000 flags: 0x1
[ 0.093318] DMAR: Failed to map dmar1
[ 0.093351] DMAR: Parse DMAR table failure.So this error already exists in bookworm.
Most likely it is some BIOS setting for VT-d expected differently by the kernel, or something like that. So no need to discuss it in this thread.
(This goes not for the other errors from dmesg in my former report above)
Sorry for not having seen that earlier.
There will be many changes and some will not appear through apt.
Well, the testing stick is waiting for being rewritten to the final release when it is ready. It’s as simple as that.
Windows is like a submarine. Open a window and serious problems will start.
