Suspend crashing OSX?

[silliker]

Hi all.

Whenever I attempt to suspend a VM with Beta 2, OSX crashes. I get the Mac BSOD and have to power off my MBP.

Has anyone else run into this? I've opened a support request, but thought I'd check here as well.

Does /var/log/system.log contain anything interesting (apart from possibly lots of entries beginning "SMAC: FromHostIP: could not find IP")? What about /Library/Logs/panic.log or ~/Library/Logs/CrashReporter/vmware.crash.log?

[bgertzfield]

As etung mentioned, please post the information from /Library/Logs/panic.log, as it'll help us diagnose the issue.

Do you have Secure Virtual Memory enabled in System Preferences -> Security? We've seen similar issues with that feature enabled in the past.

[gscoker]

I have this problem too. Here is my crash log. It is not different from the crash log from Beta 1 under the same conditions. I am not running secure virtual memory. One question, is this a real issue with Beta 1 or did the install from Beta 2 not correctly upgrade my system from Beta 1?

Hi gscoker,

This one does seem different from the Beta 1 ASSERT. (ASSERTs are internal beta-only logic-checking code that ensure our assumptions about the behavior of the system are correct; in your case, one of them hit an error case that was unexpected and unhandled).

Are you running on a Macbook Pro or another laptop machine? Is this reproducible for you? If so, can you send me a private message as to where I can get your virtual machine?

[HPReg]

silliker and gscoker,

When the crash occurs, after you reboot, can you please run this command on your system and send us the output?

grep 'Page_Ungrab' /var/log/system.log

[HPReg]

Also silliker and gscoker, are you guys using FileVault for the home directory of the user who is running the VM?

[gscoker]

This is what I get when I grep for Page_Ungrab in system.log.

Here is a panic from Beta 1. This may not be useful in this discussion, but it shows the history of this issue for my system. The crashing on suspend has been reproducible always on Beta 1 and Beta 2.

gscoker,

Thanks. We are very interested in fixing this bug. We have never been able to reproduce this in house, but a few of you guys hit it in the field. We are trying to understand what the pattern is in the failure case.

[silliker]

Sorry for the delay. On my system, I am guaranteed to crash if I try to suspend a VM, so I'm certainly a good candidate for debugging.

This is a C2D MBP.

I do not have either filevault or secure virtual storage enabled.

As far as I can tell, this doesn't seem to be dependent on virtual machine. I haven't found one that doesn't crash upon suspending, even a VM that I create in Fusion.

Hi silliker,

Does it even happen with a blank VM that you create, power on, then suspend?

[HPReg]

silliker,

Thanks for the info. Once we understand what is going on and we have a fix for it, you will be our guinea pig

Would you mind sending us a list of all the processes that are running on your box when you run the VM before it ends up crashing? I'm wondering if another application could be cause of this issue.

[HPReg]

Can you also send us th elist of kernel extensions that are loaded with this command?

kextstat

[silliker]

I'll send a file to both of you via PM.

Creating a blank VM: So long as I suspend while the system is still in the BIOS routines, I can suspend and resume without problem.

If I assign a bootable ISO to the CDROM, once the system begins to boot if I attempt to suspend, the host system crashes.

Upon accessing the VM I tried to suspend after recovery, I get various behaviours. They have been:

\- writelocks still around, remove the write lock will allow the system to start

\- corrupted nvram, requiring the system to regenerate the nvram before boot

\- invalid suspend file, requesting me to discard the suspend file before boot

I'd be happy to try to isolate more if there are areas that you'd like me to check into.

The writelocks are leftovers from the last run, it is safe to delete them manually.

Are you running any kind of AV like ClamAV or Sophos or any software that would scan files? If so, it may be necessary to exclude some files with extensions that Fusion uses -- especially large files like .iso, .vmdk, etc.

[arang]

For what it's worth, I had the same assertion failure today, but I wasn't doing a suspend -- in fact, the system was moderately busy, with Retrospect running and one VM busy. This was on a Core 2 Duo iMac.

IMO, it's a good idea to suspend VMs before the backup or exclude the VMDKs from EMC-Retrospect's task.
