A few days ago my LMDE 64bit running on a Lenovo T500 laptop began to freeze now and then. It happens once a day or so. I am not quite sure, but perhaps it started after the major update when the new Debian was releases and update manager updated hundreds of packages.
For a period I thought it was related to my laptop running hot but it also happens long before it gets hot. Today, for example, it froze about 2 minutes after starting it.
There is not obvious cause of the system hangs. No specific program that seems to cause it, no patterns of any kind. And also no error messages or warnings - it just freezes up. I have also inspected syslog without finding anything strange at the time of the freeze.
I have noticed that the green harddisk icon on my laptop continues to indicate disk access, and at one time the system freeze happened during a skype call and interestingly enough I was able to continue the call even after the freeze, at least for a while.
I have used only level 1-3 upgrades.
Thanks in advance for any comments that can help my resolve this annoying problem.
