With a new debian linux laptop, I have just resumes from my first ‘deep’ suspend-on-ram. It takes a lot of time to resume, and internal keyboard although powered (lights on) does not function either in console or under X.

dmesg keeps logging this message:

[41485.103299] ACPI: _SB_.BAT0: _BST evaluation failed: AE_TIME

Only one kernel message:

$ sudo dmesg | grep kernel
[41309.940262] perf: interrupt took too long (3204 > 3191), lowering kernel.perf_event_max_sample_rate to 62250

long after the first ACPI messag which started just at wake up:

and just after that, first mention of keyboard error:

Any idea? This was my first session after installing new software, including synaptic and xfce4-power-manager, and switching to deep suspend-on-ram rather than s2idle: should I just reboot and hope the system will behave better next…?
