usb ports working only with pci=noacpi (bugzilla 94261)
Here all details (dmesg, lspci etc): https://bugzilla.kernel.org/show_bug.cgi?id=94261 The machine is: LENOVO 90BX0018IX/Aptio CRB, BIOS O07KT49AUS 12/18/2014 OS is a Debian Wheezy amd64. The issue is that USB ports work only starting the kernel with "pci=noacpi" parameter. Without it, nothing plugged into usb ports is detected. In particular, "lsusb" returns "unable to initialize libusb: -99". The same happens with a 3.13.11 kernel (same config). I've tried newer kernels (3.18.8, 3.19) and they show the same issue. With the difference that, with "pci=noacpi" they don't start at all. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

I don't know what was my initial mistake, but I realized very soon it was not a regression and took away the "regression" flag from bugzilla. I tried many and many kernels and all were failing. I tried also to go down from 2.6.24 version, but I had to stop rather early because at some point the kernels were incompatible with distribution (I don't remember the details since I did these tests some month ago, and later I tested only newer kernel versions). The patches you sent are for -next? for -rc? for stable? Can I try them on 3.13.11?

Re: serial console does not wake from S3 suspend
When resuming from S3 suspend, serial console starts sending garbage on the serial port. Not continuously, it sends garbage only when in local console prints a text. It stops only when the (sending) machine is shut down, or if some text is sent manually (i.e. with "cat txtfile > /dev/ttyS0"). Full details are here: https://bugzilla.kernel.org/show_bug.cgi?id=69751 The problem is still present in 3.14.4, 3.15-rc7 and today's next. I hope someone is going to look at this bug. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
