https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=190186 jan.kokemueller@gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jan.kokemueller@gmail.com --- Comment #15 from jan.kokemueller@gmail.com --- When I test the new i915 code (r270990 snapshot iso or backported to 10-stable, doesn't matter) on my gen4 Intel GPU (GMA 4500MHD), I'm getting reproducible interrupt storms from "irq16: uhci0" after loading the i915kms module. It does not matter if I start X or not. This looks very similar to the situation here: https://lists.freebsd.org/pipermail/freebsd-hackers/2014-June/045369.html Setting hw.drm.msi=0 in /boot/loader.conf doesn't help. One suspend/resume cycle makes the problem go away. When I revert commit r270516 (the opregion changes) the problem goes away, too. Then there is no irq16 at all in the output of "vmstat -i". Some more info: $ grep 'irq 16' /var/run/dmesg.boot vgapci0: <VGA-compatible display> port 0x1800-0x1807 mem 0xf2400000-0xf27fffff,0xd0000000-0xdfffffff irq 16 at device 2.0 on pci0 uhci0: <Intel 82801I (ICH9) USB controller> port 0x1820-0x183f irq 16 at device 26.0 on pci0 sdhci_pci0: <JMicron JMB38X SD> mem 0xf2300400-0xf23004ff irq 16 at device 0.2 on pci2 pcib2: <ACPI PCI-PCI bridge> irq 16 at device 28.1 on pci0 pcib6: <ACPI PCI-PCI bridge> irq 16 at device 28.5 on pci0 pciconf -lvc for vgapci0: vgapci0@pci0:0:2:0: class=0x030000 card=0x213a17aa chip=0x2a428086 rev=0x07 hdr=0x00 vendor = 'Intel Corporation' device = 'Mobile 4 Series Chipset Integrated Graphics Controller' class = display subclass = VGA cap 05[90] = MSI supports 1 message enabled with 1 message cap 01[d0] = powerspec 3 supports D0 D3 current D0 Should I open a new bug?
