Seemingly Random hard freeze

Hi everyone,
I have been struggling with a very annoying problem for the last 2 months: for no apparent reasons, my computer freezes completely.
I have tried the REISUB trick unsuccessfully. The magic keys are not responding while it is frozen, and only a hard reboot on the power button managed to do something.

Once rebooted, there are no traces in the log. Absolutely nothing weird. I will post the content as soon as I have another freeze, but it looks like nothing has been written as dmesg or everything.log has no entry past the freeze time.
I also have conky running on the side and I can see no problem with the CPU, RAM, or temperature. The computer is definitely not running at a high frequency.

Configuration:

 lspci
00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09)
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04)
00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05)
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05)
00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5)
00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b5)
00:1c.5 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 6 (rev b5)
00:1c.6 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 7 (rev b5)
00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05)
00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 05)
00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05)
00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05)
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)

My next idea is to wait for another freeze, post a log here, and also try to ssh in while frozen.
If you have any idea, thank you for sharing. I am very close from just deleting the partition and re-installing everything.
Best,

I have tried the REISUB trick unsuccessfully. The magic keys are not responding while it is frozen, and only a hard reboot on the power button managed to do something.

REISUB is deactivated in a standard Arch installation.

Re: Seemingly Random hard freeze

Reinstalling is unlikely to help. Does it work if you disable GPU acceleration?

@Head_on_a_Stick Sorry should have precised: I reactivated the magic keys and they work when I am not frozen.

@Alad. No did not think of that. Trying.

Thank you so much for your responses!

EDIT: so far no freeze since I disabled GPU acceleration. Looks promising.

Re: Seemingly Random hard freeze

So I had another freeze two days ago while I was using the "NoAccel" option,
and another one today despite having disabled 3D acceleration.
I then had another freeze while I rebooted and wpa_supplicant was starting, but not sure if related.

Here is my entire log of this period. I am going to get through it on my side and hopefully trim it.

Though I got to say that the freeze have been a lot less frequent with DRI disabled.

Roxas, could you take a look at this thread of mine. I don't think our issues are related, but I would like your opinion on that.

Re: Seemingly Random hard freeze

This could be the issue:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)

What kernel are you running? You should try the linux-mainline kernel, maybe this fixes the freezes.
Or you could unload the Realtek module.

The reason why I'm pointing to the Realtek driver, is that I also have freezes on my tablet when using the Realtek driver.
Unfortunately the tab broken at the moment (doesn't enter recovery), so I cannot test.

Re: Seemingly Random hard freeze

Thank you guys for your answers.

@beta990 I am running the standard kernel from the core repo, up to date 3.19. I am probably going to fiddle with the Realtek module then and see what happens.

@nstgc Your problem just went way over my head. Need to brush up.
