Kernel error kernel:[360783.353677]

Did you do this:

Try to disable APM and ACPI in CTRL+ALT+T menu(in console mode ).ctrl+alt+t->boot options(9)->Boot parameters(1).

I did, and I also disabled all ACPI functions in the machine's BIOS.
Furthermore, I've replaced the power supply yesterday and moved the SSD to the Areca Controller, to see if the onboard SATA controller might be the problem.

By the way -just for the information of others-, after moving the disk from the onboard controller to the Areca controller, another reboot was required before I could reconnect the Volume to the iSCSI target, but it worked surprisingly well.

Unfortunately, this morning the machine went down again, and not being home, I haven't had a chance to reset the machine and look at the logs.
Tonight, I'll bring the machine back up, check the ACPI settings, examine the log and post my findings here.

Are there any logs beside the dmesg.2 and critial_errors.log (so far: this was always empty) files that I should examine?

P.s. I found two other forum threads in which similar behavior is mentioned: here and here. With reference to the first, recalling when the freezes started, I think it was after upgrading above v6 update 90.
Unfortunately, in neither thread a final outcome is reported.

One of the links show a solution by replacing disk(s) with errors, after that the system start to work fine.
So we recommend you to check your controller health and to check the storage disks, then to run file system repair tool to fix your FS if it contain any issue.
Please check this KB: http://kb.open-e.com/File-system-repair_138.html

Also please be sure that your controller Firmware is updated to the latest firmware available at your controller website.

Thanks for the hints: I've checked the controller's and disks' health and no issue was found. All are running the latest firmware builds.
However, I found that the ACPI features were still turned on in the boot options - I guess I turned them off before upgrading to v7 and forgot to check afterwards.
I turned it off and rebooted.

The machine is up and running again and I keep my fingers crossed...
Thanks for your help and I'll keep this thread up to date so it might be helpful for other users (although maybe just the inexperienced users like me).

FYI: driver settings, and boot settings and a few more, are not saved when going from DSS V6-->DSS V7. I thought this was in the release notes someplace. Guess I will have to check on that!

[Arcesilaus]

I'm sure it's in there: I probably just did not pay enough attention when upgrading

Unfortunately, keeping the fingers crossed did not help: even with having ran a full memtest (no errors), completely disabled the onboard SATA controller and the ACPI features turned off, the system hang again last night.
I rebooted and checked the error logs, but I could not find a clue what happened.

It feels like I'm slowly running out of ideas...
Anyone willing to take a look at my logs and see if I overlooked something?

[danielweeber]

yeah, for sure.

How do you see that it is a system freeze? Is it a actual freeze? Or is it something like: WebGUI not available, Console behaving slow and strange?
