Last Dec (2012) my MacBook Pro (OS X Lion) started freezing, say 3 or 4 times a session. I ran both the Apple hardware diagnostic DVD (ran for hours, no problems), and I ran a disk scan, no problems found.
The kernel.log message turns up these messages, at every single crash:
Dec 13 07:29:27 Gord-Waits-MacBook-Pro kernel[0]: CODE SIGNING: cs_invalid_page(0x1000): p=809[GoogleSoftwareUp] clearing CS_VALID
Dec 13 07:41:17 Gord-Waits-MacBook-Pro kernel[0]: CODE SIGNING: cs_invalid_page(0x1000): p=839[ksadmin] clearing CS_VALID
Dec 13 07:41:18 Gord-Waits-MacBook-Pro kernel[0]: CODE SIGNING: cs_invalid_page(0x1000): p=840[ksadmin] clearing CS_VALID
If you google for GoogleSoftwareUp you find a number of internet posts with the same problem. I found one page that suggested I turn off the update by issuing this command:
defaults write com.google.Keystone.Agent checkInterval 0
which is supposed to disable auto google updates completely.
That drastically reduced the crashes, but I still get a crash about once or twice a week, with the same Google Update related messages.
Anyone have any new ideas?
I suppose I should uninstall Chrome altogether next..
