So I have here the latest interrupts before I rebooted. 0: 37799577 0 IO-APIC-edge timer 1: 309 0 IO-APIC-edge i8042 6: 47784 0 IO-APIC-edge lirc_ite8709 8: 1 0 IO-APIC-edge rtc0 9: 11984 0 IO-APIC-fasteoi acpi 12: 1074 0 IO-APIC-edge i8042 16: 276919 0 IO-APIC-fasteoi uhci_hcd:usb2, nvidia 18: 1315728 0 IO-APIC-fasteoi uhci_hcd:usb8, jmb38x_ms:slot0, ohci1394, mmc0 19: 1579638 0 IO-APIC-fasteoi ata_piix, ata_piix, ehci_hcd:usb1, uhci_hcd:usb4, uhci_hcd:usb7 21: 0 0 IO-APIC-fasteoi uhci_hcd:usb3 22: 3305783 0 IO-APIC-fasteoi HDA Intel 23: 2 0 IO-APIC-fasteoi ehci_hcd:usb5, uhci_hcd:usb6 216: 3033526 0 PCI-MSI-edge iwl3945 217: 9101163 0 PCI-MSI-edge eth0 NMI: 0 0 Non-maskable interrupts LOC: 6434802 22944923 Local timer interrupts RES: 1790955 4134157 Rescheduling interrupts CAL: 1564485 2469460 function call interrupts TLB: 43600 45062 TLB shootdowns TRM: 0 0 Thermal event interrupts SPU: 0 0 Spurious interrupts ERR: 0 MIS: 0 I'm also joining the chart from collected /proc/interrupts each minute during ~870 minutes (with a simple script) created with OOo. basically I see nothing very unusual on it. Just to note: 870th minute is around 18:30. Resume from s2ram is at 375th minute (9:15 morning). I closed all browsers and went out for skiing at around 12:30 (I left only Azureus open). So the ksoftirqd problem appeared when I was out. There is little change in slope at minute 450 (11:30), except the "eth0" curve (3rd from top). In var/log/messages there is nothing unusual, only classic dhcprequest stuff (same as in previous post). I also realized now that the minutes aren't extra accurate (just a sleep 60) which can add some error. regards. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Did you try to update to the newest kernel (2.6.28.x)? It solved this for me (at least I didn't have any problems so far). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Note that the cause for the ksoftirqd overload during normal operation will be different from that kind of artificially triggered one (and more severe because of hdd-access overload). To test with it type:

make install (on a 64bit machine) /usr/sbin/piguicqt (as root)
