Dear Maintainer,
As of a sid full-upgrade two days ago (Tue Oct 25), I'm seeing two
regressions on my Lenovo Carbon X1 gen7:
- systemctl suspend no longer works: instead of suspending, it freezes,
and I have to hold the power button for 10 seconds to force a power down
- the laptop's built-in sound card (intel, using the firmware-intel-sound
package) is no longer seen. In dmesg there's a "failed to instantiate
card" error
Both of these were working fine as of a system update a day or two earlier.
The problem seem to be due to 6.0.0-2-amd64. If I reboot into my old
kernel, 6.0.0-1-amd64, the sound card is found and suspend works.
I hope it's not too presumptuous to put these both in the same error
report; they seem very different but they happened at the same time
and they're both cured by using the old kernel.
For the suspend problem, I'm not sure how to debug a freeze or what
additional info would be useful, but I'm happy to run any tests you suggest.
For the sound card problem, pacmd list-sinks prints what seems to be a
placeholder in the absence of finding an actual sound card (and the same
for list-sources, it doesn't see the mic either):
