Previous to this kernel update, the machine failed to wake from suspend, when plugged in, almost every time. Most often it resumed from suspend when unplugged from power. With the current kernel update, the machine will not enter suspend, or seems to hang immediately.

Here is the output from amd_s2idle.py:

I tried updating to the beta 3.07 BIOS, as there was mention of fixes around sleep, however, that seems to change nothing.

I strace’d amd_s2idle.py to see why it was failing to suspend, and found this:

openat(AT_FDCWD, "/sys/power/state", O_WRONLY|O_CREAT|O_TRUNC|O_CLOEXEC, 0666) = 26
fstat(26, {st_mode=S_IFREG|0644, st_size=4096, ...}) = 0
ioctl(26, TCGETS, 0x7ffd6b2ed830)       = -1 ENOTTY (Inappropriate ioctl for device)
lseek(26, 0, SEEK_CUR)                  = 0
lseek(26, 0, SEEK_CUR)                  = 0
write(26, "mem", 3)                     = -1 EBUSY (Device or resource busy)
write(26, "mem", 3)                     = -1 EBUSY (Device or resource busy)
close(26)                               = 0
getpid()                                = 6311
write(3, "2025-03-11 22:43:09,682 ERROR:\t\342"..., 53) = 53
write(1, "\342\235\214 \33[91mFailed to suspend\33[0m\n", 31❌ Failed to suspend
) = 31

It looks like the system controller is failing to enter sleep.
