Hello all, I have get an issue after recent kernel recompile. The problem appears after switch from X to text console and back to X11. After that vmstat -i show an interrupt storm on cardbus device: > vmstat -i interrupt total rate irq1: atkbd0 6483 3 irq9: acpi0 3236 1 irq12: psm0 347988 167 irq14: ata0 16431 7 irq16: cbb0 uhci2+ 13624982 6556 irq20: uhci0 14 0 irq22: ehci0 2 0 cpu0: timer 4154687 1999 irq256: em0 53736 25 irq257: hdac0 5797 2 cpu1: timer 4153683 1998 irq258: vgapci0 235585 113 Total 22602624 10877 I suppose that the issue related with the latest MSI interrupt handler changes for intel graphics chipset. My laptop has i965GM. pciconf -lv: vgapci0_at_pci0:0:2:0: class=0x030000 card=0x20b517aa chip=0x2a028086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'Mobile 965 Express Integrated Graphics Controller' class = display subclass = VGA When I added my device to drm_msi_blacklist and recompile drm modules the problem disappear. Is it possible to resolve this problem without moving the device to the drm_msi_blacklist? I can test any patches or provide additional detail if it is required. Thanks. -- Best Regards, Nasonov SergeyReceived on Fri Feb 27 2009 - 13:55:50 UTC
