--- Comment #18 from WZab <w...@ise.pw.edu.pl> 2012-09-04 08:36:03 --- I've performed yet a few tests with selective removal of drivers using the I2C interface. I've found, that if I remove both: i915 and nouveau drivers, the system boots with USB disk connected to USB 3.0 connector. If ANY of those drivers remains, the system freezes, when booting with USB disk connected to the USB 3.0 connector. This finding undermines my theory, that problem is associated with sharing of IRQ 18 line, as e.g. both xhcd and i915 driver use the MSI interrupts: # cat /proc/interrupts [...] 41: 1 0 0 0 0 0 0 0 PCI-MSI-edge xhci_hcd 42: 0 0 0 0 0 0 0 0 PCI-MSI-edge xhci_hcd 43: 0 0 0 0 0 0 0 0 PCI-MSI-edge xhci_hcd 44: 0 0 0 0 0 0 0 0 PCI-MSI-edge xhci_hcd 45: 0 0 0 0 0 0 0 0 PCI-MSI-edge xhci_hcd 46: 0 0 0 0 0 0 0 0 PCI-MSI-edge xhci_hcd 47: 0 0 0 0 0 0 0 0 PCI-MSI-edge xhci_hcd 48: 0 0 0 0 0 0 0 0 PCI-MSI-edge xhci_hcd 49: 1487 0 0 0 0 0 0 0 PCI-MSI-edge eth0 50: 35106 0 0 0 0 0 0 0 PCI-MSI-edge ahci 51: 436 0 0 0 0 0 0 0 PCI-MSI-edge iwlwifi 52: 899 0 0 0 0 0 0 0 PCI-MSI-edge i915 -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
