Description Federico Mena Quintero 2007-08-14 15:02:56 UTC

This seems to be the same as bug #191903, but for 10.3.  Main-menu uses 100% CPU when unsuspending.  I think NetworkManager is sending it thousands of notifications while it reconnects (it shouldn't!), and then main-menu wants to regenerate its icons or something.

Comment 1 Mark Gordon 2007-08-14 18:42:54 UTC

Any evidence of such notifications? What network hardware/driver do you have?

Comment 2 Federico Mena Quintero 2007-08-14 20:50:58 UTC

Just a Thinkpad T42p with the Intel ProWireless stuff.

If you get a stack trace of the code while it is spinning, you'll see that the only way that code can execute is through a NM notification.  Actually, the NetworkManager daemon shares the CPU load with main-menu:  about 30% NM, and about 70% main-menu (though of course it varies).

Comment 4 Petr Baudis 2007-09-11 15:02:25 UTC

This can make the system quite unusable for the portion of users not skilled enough to kill mainmenu manually in large portion of suspend/resume cases. I think this should be marked critical.
