I have only seen this for SMP, PREEMPT_NONE. This same error also occurs in 3.6.7 without the RT_PREEMPT patches applied, so this does not appear to be an RT_PREEMPT issue. This error also occurred in the previous smoke test of linux-3.6.7-rt18 http://permalink.gmane.org/gmane.linux.rt.user/9202 The boot error starts with the USB time out on ep0out: [ 3.264373] smsc95xx 1-1.1:1.0: usb_probe_interface [ 3.269500] smsc95xx 1-1.1:1.0: usb_probe_interface - got id [ 3.275543] smsc95xx v1.0.4 [ 8.078674] smsc95xx 1-1.1:1.0: eth0: register 'smsc95xx' at usb-ehci-omap.0-1.1, smsc95xx USB 2.0 Ethernet, 82:b9:1d:fa:67:0d [ 8.091003] hub 1-1:1.0: state 7 ports 5 chg 0000 evt 0002 [ 13.509918] usb 1-1.1: swapper/0 timed out on ep0out len=0/4 [ 13.515869] smsc95xx 1-1.1:1.0: eth0: Failed to write register index 0x00000108 [ 13.523559] smsc95xx 1-1.1:1.0: eth0: Failed to write ADDRL: -110 [ 13.529998] IP-Config: Failed to open eth0 The boot error can be avoided with a workaround that simply retries the failed USB command. I will reply to this email with the patch. -Frank -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
