I'm trying to allocate memory from 4GB-8GB range and have modified the memory structure(QH,iTD etc) to support 64 bit addressing. I am constantly hitting the following issues and I am not sure about the exact meaning of the error message(timed out waiting for BIOS). ehci1: [ITHREAD] usbus0: waiting for BIOS to give up control usbus0: timed out waiting for BIOS<---Issue 1) ---what does this error message mean?? usbus0: EHCI version 1.0 usbus0: run timeout<--Issue 2) ---message is coming from ehci_init function, EHCI_STS_HCH bit is set in the status register?? ehci1: USB init failed err=18 Following solution has been posted for issue 1 but I couldn't see such option in the BIOS that I am running on. http://forums.freebsd.org/showthread.php?t=18783 -- View this message in context: http://freebsd.1045724.n5.nabble.com/USB-DMA-memory-Allocation-tp5833506p5835461.html Sent from the freebsd-usb mailing list archive at Nabble.com.
