lgskyxp Posted December 2, 2011 Share Posted December 2, 2011 hi guys, i met the high cpu usage in my PC(vaio VPCS131FM) while using the win7, thanks to the guide from i captured some runtime trace information. The interrupt CPU usage show that there are too many HalpProfileInterrupt handling(sorry, i didn't find the place to upload picture), then ntoskrnl.exe:ExpWorkerThread spend too many time on that. After googling HalpProfileInterrupt, it seems this interrupt is related to APIC Profile(APIC_PROFILE_VECTOR), is there anyone get into the same problem before? can anybody give me any hint on that? thanksBTW: i met same problem before, but more serious, the sympton is that i got tooooo many interrupt from, for example, pci-e memory stick host controller. After uninstall the VMware-player-3.1.4, the system got back almost, except the problem as above. Link to comment Share on other sites More sharing options...
