[Bug 1313981] Re: Kernel disabling serial port ttyS0 on boot
I am surprised the importance of this bug is only medium. A lot of important devices stopped working for us - contactless card readers (ACR120), USB scanners (Canon LIDE models)... Thankfully, kernel 3.16 really does fix the issue. For us, the bug manifested in kernels 3.2, 3.11, 3.13 using Intel Haswell desktop and mobile chipsets (B85, H81, H87, C220) on both USB 2.0 and 3.0 ports using 32-bit or 64-bit Ubuntu 12.04 and 14.04. Kernel 3.16 fixes this on all mentioned ports, chipsets and OS versions. Honestly, thanks a lot to everyone here, and I hope more people will find this bug thread... and ideally that the fix will get backported to older kernels (especially 3.13 since it's the current Ubuntu LTS one). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313981 Title: Kernel disabling serial port ttyS0 on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1313981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok this disabled message very likely is coming from pnp_stop_dev(), and most probabally coming from a probe failure in pnp_device_probe(). This implies we can either not match the device to any driver, or the probe itself failed for some reason, the lack of any error between the two quoted lines tend to imply the former. So. We need to know the device type and which driver normally binds to it.

[Bug 1313981] Re: Kernel disabling serial port ttyS0 on boot
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.

[Bug 1313981] Re: Kernel disabling serial port ttyS0 on boot
Because I require the serial port in production I downgraded to 13.10 and all testing I do will be through a live usb boot. Assuming I can figure out how to customize the live usb to use the mainstream kernel I will test it.

For what it's worth, I was able to boot with mainline v3.14.1-trusty kernel: bug still existed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313981 Title: Kernel disabling serial port ttyS0 on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1313981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
