Apologies for the repeat posting--I think my previous posting ended up bouncing due to some misconfigured dmarc settings. Anyways, I have kind of a weird issue that I'm having trouble debugging. On my MacBook Pro (11,1), checking battery status (through acpi or the /sys filesystem) becomes extremely slow after the computer's been on for a while. Here's an example:
$ time cat /sys/class/power_supply/BAT0/status Charging real 0m54.519s user 0m0.000s sys 0m4.663s dmesg and journalctl aren't outputting anything during the call, and I tried strace during the command and there was no output during the blocked time. It's highly intermittent--acpi can take anywhere from 0-60 seconds with no discernible pattern, except that it doesn't happen when the battery is plugged in and charged. Any ideas for how to debug this further, or possible solutions? Thanks so much!
