Description of problem: Fedora 23 does not come up on a T500 with latest Fedora 23 kernel 4.4.4-301 Version-Release number of selected component (if applicable): 4.4.4-301 How reproducible: Install the named kernel on a Lenovo T500 (probably similar) on Fedora23 Steps to Reproduce: 1. Update kernel to 4.4.4-301 2. Reboot Actual results: System does not come up. Remote execution using my own means (openvenus, see on sourceforge), not depending on other stuff like ssh, shows, that scripts are hanging waiting for lspci to finish, which in turn is in an "open" system call on /sys/bus/pci/devices/0000:01:00.0/config which is booted with 4.4.3-300 00:01.0 PCI bridge: Intel Corporation Mobile 4 Series Chipset PCI Express Graphics Port (rev 07) Expected results: system comes up and is usable Additional info: this is the Laptop of my wife. I think when things are not getting better i'll buy some Windows license.
The last lines i see during boot on the screen: Starting Show Plymouth Boot Screen Starting dracut initqueue hook then nothing happens anymore.
Can you get any kind of dmesg output from whatever you are using to trace the calls? Does any earlier kernel work? Please also share the full output of lspci from your system.
As i wrote, with kernel 4.4.3-300 and earlier ones the system comes up. Obtaining an lspci output is not possible with 4.4.4-301. strace shows, that lspci hangs in the system call open with /sys/bus/pci/devices/0000:01:00.0/config as first argument. So the attached lspci output is obtained with 4.4.3-300 booted.
Created attachment 1136373 [details] lspci output obtained with older kernel booted
Created attachment 1136374 [details] dmesg output in the status when the system does not come up with 4.4.4-301
Created attachment 1136375 [details] strace of lspci in the hanging status when booted with 4.4.4-301
Additional Info: When in the hanging status, the laptop must be reset hardly by holding down the power button for several seconds. Even reboot -nf does not work.
There was a known Radeon issue, can you please test http://koji.fedoraproject.org/koji/taskinfo?taskID=13347691
There were actually two issues. If that one doesn't work, please test http://koji.fedoraproject.org/koji/taskinfo?taskID=13356645 as well
The 2nd fix is required, then the system comes up normally again. Thank you. The only thing that looks unusual to me is, that the "plymouth boot screen" bubble does not show after the display has switched to the higher resolution. What i would like to know, why this had to be broken.
