Confirmed. 6.19.0-9-generic works fine when installed on an existing
system but the casper initrd of the ISO seems broken. Missing module or
firmware?

** Also affects: linux (Ubuntu Resolute)
Importance: Undecided

Title:
Ubuntu Resolute Desktop image arm64 - Boot on SC8280XP stalls with
gpi-dma errors

Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Resolute:
Confirmed

Bug description:
Booting the https://cdimage.ubuntu.com/daily-live/pending/resolute-desktop-arm64.iso from 02/14/26 and 02/14/21 on The Lenovo Thinkpad X13s or Windows Dev Kit 2023 don't boot. They either reset or stall. Both devices boot nicely with the Ubuntu Concept X1E kernel 6.19.0-6, but on the installed Ubuntu 25.10 from internal SSD.
Digging a bit, I can see these dmesg lines when booting up (after init, shortly after speed-test for RAID6, as it seems after async_tx_init:

gpi 800000.dma-controller: Error with cmd: CH START completion timeout
gpi 800000.dma-controller: Error with cmd: DE ALLOC ret:-5

The WDK resets shortly after that, the X13s stalls. Bouth don't reach
a login.

My guess is its somewhere in the udev rules or init script, as the
same kernel runs fine on 25.10.
