Hi guys,

A bit about my system:

* Stock Dell Mini
* 16GB SSD
* 10.5.6
* DellEFI 1.1
* Legacy USB + wake have been disabled

Now my problem:

When I close the lid / sleep and come back, OSX responds normally for about 2-5 seconds. Then the spinning wheel just stays and won't go away. I can still Apple-tab to swap apps, and often I can still right click on the wireless to see what networks are visible but most left clicks won't work.

It doesn't seem to stop responding until you let the screen go blank as per your energy saving settings then it will never wake up (power light is fixed on).


Appreciate any pointers

Cheers,
Tim

You could try opening a Terminal before going to sleep. Then do a 'tail -f /var/log/system.log'

Also, a couple of suggestion, if you have iStat installed, remove it. Make sure AppleTalk is disabled.

to be safe re-install dellefi app or use a different rev of it to make sure its not some weird bug from an older or newer ver... I use 1.0.7.1 myself and have no sleep problems. my bios version is A00 which is why have not tried the newest efi release , I think you need A04 for that one...

Hi guys,

Thanks for the promp responses, in reply:

1. Appletalk is disabled for Airport and ethernet.

2. I've tried reinstalling DellEFI 1.1 multiple times but not reverting to <1.1 as I was concerned about incompatibility with 10.5.6 and it freezing on startup ops: But I have tried advanced settings on 1.1 final and selecting various things (but none of the "not recommended" options)

3. Doing the tail -f /var/log/system.log probably found out what the issue is..

When you wake from slepe there's a bit of chatter but this is repeated 7 times amongst some other things:

disk0s2: I/O error.

Which is my SSD drive main partition...

[FrankB]

Yeah that would do it. Time to contact Dell.

Hey Frank,

I ran tdisk utility "verify disk" check and nothing comes up as being bad - I'm kind of puzzled why it would be a hardware failure if OS X seems to run flawlessly otherwise.. ?

hey guys, i have a 32 gb stec running dell efi 1.1 w/ bios a05.

I have the same exact type of error where this happens right out of sleep. i dont think this is the SSD's fault because i only have this happen when i come out of sleep. it hasnt happenned before when i was copying files around...

I wonder if anyone else can shed some light on this?

[Timmy G]

Yeah, I've subsequently booted off the OS X installer USB I have and run Disk Utility when disk0s2 is unmounted to check/repair and nothing bad really came up (just some permissions are wrong messages), so I don't think it is fault hardware..

Appreciate any other ideas!

One thing that did cause this for me was having iStat Menus installed, with the Intel temperature sensor extension. The latter tries to get lots of hardware information for stuff the Mini 9 doesn't actually have but the software assumes it has (fans, temperature sensors) and under certain circumstances it locks up.

The solution in my case was to completely deinstall iStat Menus and its support directories in /Library and ~/Library.

Because I missed the functionality, I tried MenuMeters, which was rock solid stable. However, I found that although it worked, MenuMeters didn't give as much information (e.g. top CPU-hogging processes) so I have since reinstalled iStat menus *without* the Intel extensions. This means I can't sense temperatures or fan speeds, but as there is no fan and the temperature sensor didn't work anyway, that's actually no loss at all. It's only been 24 hours so far, but it seems stable. I've had one lockup, but I think that was due to something else.

If this is your problem, then it's pleasantly easy to solve. Otherwise.... good luck!

The only thing that comes to mind is to verify that you are using the correct AppleIntelPIIXATA.kext. There is a fix in it to reset the SSD after sleep which allows the STECs to sleep. Although I'm not quite sure how to do this.

On a Mini, it's:
kextstat | grep AppleIntelPIIX
54 0 0x31f2b000 0x9000 0x8000 com.apple.driver.AppleIntelPIIXATA (2.0.0)_ <53 17 6 4>

But on my MacBook Pro it's:
37 0 0x5b322000 0x9000 0x8000 com.apple.driver.AppleIntelPIIXATA (2.0.0) <36 17 6 5 4>
