Could you give your hardware details? At least, give the output of hwinfo. Also, check journalctl output whether you get any kernel Oops / panic snippet in previous boots. -- You are receiving this mail because: You are on the CC list for the bug.

I have an ASRock Z87E-ITX, with the half mini-PCI Express slot filled with an Intel Centrino Advanced-N 6235 instead of what came with the board. The CPU is an Intel Core i7-4770S. Nothing is in the PCI Express slot (hence using the built-in graphics). I have a couple SSDs, one HDD, and my internet is through PPPoE via an Ethernet to USB adapter. I have attached my hwinfo. journalctl was not informative (at least not to me). A hang looks something like: ...

My system has been stable before. Leap 42.1. Kernel is 4.1.20-11-default. System is updated by default (whenever yast wants to upgrade :-)). As far as I read the referenced forums etc., is there a final solution/suggestion for this issue? Should I upgrade to a newer kernel or use the "AccelMethod" "uxa" workaround? -- You are receiving this mail because: You are on the CC list for the bug.

Your problem may look similar, but it's likely a different problem. 4.1.20 had a known problem in USB, and this got fixed in 4.1.21. But better to try 4.1.25 in OBS Kernel:openSUSE-42.1 repo.

I was too fast. Today two (2) freezes and reboots, one during a "Back in Time" backup session, while writing on an NTFS USB 3.0 external HDD. Last time it took me DAYS to recover the disk from an old XP box and CHKDSK :-(((((((( Added OBS Kernel:openSUSE-42.1 repo, prio 20. Upgraded to 4.1.25 as written. Multiversion kernels are enabled, latest, running and 4.1.13-5.1. Tested and worked a lot since then, and 4.1.25 seemed to be stable / solving the issue. Never had a freeze with 4.1.25. But because I didn't change the repository config after that, Kernel:openSUSE-42.1 repo stayed active in prio 20, and my machine is now on 4.1.26-4.g294632f-default sinceyesterday evening, automatically. Takashi, you've mentioned a fixed in 4.1.21 USB bug, and that Cliffords problem was related to xhci_hcd. I've installed (yast's) Kernel KDUMP. Captured a freeze and/or following crash with a kernel > 4.1.13 but < 4.1.25. And have also lines with [xhci_hcd] which looked at first very similar to what Clifford uploaded before. Please advice what I should do? Should I open a new bug? -- You are receiving this mail because: You are on the CC list for the bug.
