Hi! 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. Any ideas for how to debug this further, or possible solutions? Thanks so much!
