Description Benjamin CHAINTREUIL 2015-05-14 15:54:18 UTC
Hi,

Since I have install the linux kernel 4.0 on my computer (Actually, My laptop is running the 4.0.3), I can't suspend/shutdown it at all (My previous running version was 3.16)

Now, when I run the "shutdown -h" command, my screen become blank, and after a while, fan begin to turn at its maximum capacity

As if "power off" doesn't work anymore, but "halt" yes (Even if I don't see the "System halted" message)

With dmesg, I was able to see that many ACPI exceptions has occurred during boot :

benjamin@chaintreuil:~$ sudo dmesg -t | grep -i 'error\|warn\|exception'
ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [\_S1_] (20150204/hwxface-580)
ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [\_S2_] (20150204/hwxface-580)
acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM
ACPI Warning: SystemIO range 0x0000000000002000-0x000000000000201f conflicts with OpRegion 0x0000000000002000-0x000000000000200f (\_SB_.PCI0.SBUS.SMBI) (20150204/utaddress-258)

My laptop (a Packard Bell EasyNote TF71BM-C4XZ) is running on Debian 8, with a bios in UEFI
