https://bugzilla.kernel.org/show_bug.cgi?id=214789 --- Comment #8 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) --- How many of those 90 interrupts were issued by the EHCI host controller as opposed to the card? Are there any USB devices attached to the host controller? What does /sys/kernel/debug/usb/devices have to say? Does the card use edge-triggered interrupts rather than level-triggered? Have you tried adding any debugging messages to ehci_irq to find out what's going on when it runs? -- You may reply to this email to add a comment.
