When I type on the keyboard, the text is slow to display (on the order of seconds usually). Sometimes, it doesn't show up at all. However, if I mash keys on the keyboa= rd (like Ctrl, Shift, Esc, etc), it will actually update the screen. On occasi= on when I reboot, the system will not shutdown unless I continually press keys= on the keyboard, as if the system is halting unless there is an interrupt. In addition, I am able to setup networking with SSH. When I SSH into the system, it seems to work fine remotely. I don't have any of these issue in = my SSH session. I have checked vmstat -i for interrupt storms, but the interrupt levels are normal. I have attached usbdump, dmesg, and pciconf logs below. --=20 You are receiving this mail because: You are the assignee for the bug.=
