When my battery gets too low, Ubuntu will suspend/hibernate. Upon waking from this state, I've found the following issues arise:
Sound crackles. alsactl init fixes this.
Touch input no longer works.
Pen input no longer works.
Doing a normal suspend and wake, or a reboot fixes these issues.
There are various existing issues similar to this like #1171, #1223. None for SP5 specifically and there are some differences: Normal suspend wakes fine. It's only waking from hibernate suspend that is causes these issues.
Environment
Hardware model: Surface Pro 5
Kernel version: Linux tablet 6.7.2-surface-1 #1 SMP PREEMPT_DYNAMIC Tue Jan 30 00:35:58 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
Distribution: Ubuntu 23.10
`dmesg` output. `[ID-N]` are various identifiers I've replaced. There's some `surface_acpi_notify` events showing errors and a bunch of `ipts` failures at the end after waking.
