I updated Slackware 14.2 64-bit on my Thinkpad T400. I no longer can suspend the system.
Looking into the logs indicates the regression is at line 301 in
/usr/lib64/pm-utils/pm-functions:
Code:
echo mem > /sys/power/state
Trying to execute that same command in a terminal results in:
Code:
echo: write error: Resource temporarily unavailable
Permissions of
/sys/power/state are 644 with the contents of
freeze mem disk.
Suspend works fine when booting with 4.4.111, but that has
a regression with the e1000e kernel module.
Anybody else seeing this regression?
Edit: Rebuilding acpid and pm-utils against the new kernel and gcc did not help. Compiling acpid 2.0.28 did not help.
Edit: Suspend works with the 4.4.113 and 4.4.114 kernels. Looks like the regression appeared in 4.4.115. I compiled the 113 and 114 kernels with the new gcc.
Edit: The bug affects all three of my Intel systems: 1) Quad core Intel Core i5-6400, 2) Intel Celeron 1037U, 3) T400 Dual core Intel Core2 Duo P8400
