Dear Maintainer,



I have a machine running Trixie where a wireplumber process owned by Debian-gdm
is started that uses 100% cpu of one core. While the process is running I get a
series of messages in my log saying

'INFO: task daemon-init:1972 blocked for more than 966 seconds.
[ 1088.843557]       Not tainted 6.12.30-amd64 #1 Debian 6.12.30-1
[ 1088.843559] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this
message.
[ 1088.843561] task:daemon-init     state:D stack:0     pid:1972  tgid:1948
ppid:1      flags:0x00004002'

followed by a Call Trace. My virtual machines do not start while the process is
running and I cannot login over gnome-remote-desktop (system level).

GDM is running on the physical machine and if I log in there and start gnome
the process disappears and everything afterward behaves as expected, including
gnome-remote-desktop. If I simply kill the process from a terminal I am *not*
able to log in over gnome-remote-desktop.

I did a complete reinstall of Trixie after the problem first appeared. All
behaved well for the first few days after that but then it re-appeared this
morning on a fresh boot (and multiple reboots).
