--- Comment #63 from katabami <[email protected]> 2011-10-02 00:21:14 PDT --- Hi. I noticed one peculiar thing: IRQ 19 (radeon's) is almost always frozen at 200001 times: $ cat /proc/interrupts CPU0 0: 409332 IO-APIC-edge timer 1: 448 IO-APIC-edge i8042 8: 0 IO-APIC-edge rtc0 9: 178 IO-APIC-fasteoi acpi 12: 73159 IO-APIC-edge i8042 16: 22757 IO-APIC-fasteoi ahci, hda_intel 17: 9173 IO-APIC-fasteoi ohci_hcd:usb3, ohci_hcd:usb4, ohci_hcd:usb5, ohci_hcd:usb6 19: 200001 IO-APIC-fasteoi radeon 23: 2 IO-APIC-fasteoi ehci_hcd:usb1, ohci_hcd:usb2 42: 30400 PCI-MSI-edge eth0 NMI: 0 Non-maskable interrupts LOC: 173250 Local timer interrupts SPU: 0 Spurious interrupts PMI: 0 Performance monitoring interrupts IWI: 0 IRQ work interrupts ERR: 0 MIS: 0 And it seems when it reaches that number, dmesg "irq 19: nobody cared" appears, though not sure. I've also seen the number 300001, only once during several rebooting. Except this time, all was 200001. Why step of 100000?? But Phil Cole said above that he has 2 cpus, and the threshold of the attachement[1] was 281. [1]https://bugs.freedesktop.org/attachment.cgi?id=47380 "noapic" boot option doesn't help. I tried it only once, and it showed: 11: 200002 XT-PIC-XT-PIC ehci_hcd:usb1, ohci_hcd:usb2, radeon (Without noapic, the ERR interrupt is always 0, but with noapic, ERR increases.) Let me add one more issue, module vs built-in: when I compile the driver "radeon" as a module, kms starts. But if it's built into the kernel, it freezes at the boot time, showing black screen. Keyboard is ignored, and HDD access LED doesn't turn on. I've checked it's the only difference. (In menuconfig, CONFIG_DRM_RADEON being "m" or "y". In the .config file this option will automatically pull in several other flags.) I tried boot options below, but none worked: "irqpoll", "ioapicreroute", "nohz=off processor.max_cstate=2". (In the past, the last one was necessary for my HP Compaq 6715s, but recent kernels do't require it.) -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
