------------------------------------------------------------------------------------------------------------------------------------------------- And this cycle keeps on repeating. Does it looks like a hardware problem or some issue in driver configuration or some thing else. Also I wanted to understand the meaning of following variables: #define EHCI_IAA_JIFFIES (HZ/100) /* arbitrary; ~10 msec */ #define EHCI_IO_JIFFIES (HZ/10) /* io watchdog > irq_thresh */ #define EHCI_ASYNC_JIFFIES (HZ/20) /* async idle timeout */ #define EHCI_SHRINK_JIFFIES (HZ/200) /* async qh unlink delay */ Does they any impact on the performance?
