https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209099 Bug ID: 209099 Summary: ata2: already running! panic: bad link elm 0xfffff80003b7e6a0 prev->next !=3D elm Product: Base System Version: 11.0-CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: furstenwerth@gmail.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Created attachment 169760 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D169760&action= =3Dedit Image of Screen showing panic. I have been battling a bug for about 4 months now. This has spanned 10.2-release, 10.3-release, 11-current. If I could get some assistance here= in how to trace this problem I would gladly provide information. Known Good State: FreeBSD 10.2-11-current, works flawlessly. Bad State: Install py27-salt, run minions and or master.=20 Note: tested only on my hardware, but reproducible.=20 Steps to reproduce, run in ide compatibility mode or hardware that cannot do AHCI. Install FreeBSD 10.2-11-Current Install py27-salt run 'salt machine test.ping' Machine will then report. run 'salt machine state.apply test=3DTrue' Everything reports properly run 'salt machine state.apply'=20 Expected behavior is report back of success, observed behavior is kernel pa= nic. I get a very limited window that I can do any input to the machine. At this time I cannot boot past starting jails as salt minion loads previously. I cannot verify who this impacts, I cannot verify the extent of it as I have = read zero data regarding this specific to salt. I can replicate this, I can reproduce it across multiple machines.=20 Changing one machine from AHCI to IDE will induce this as well, that machin= e is now stable for weeks without issue. Sadly the two machines that are causing= the headache have no allocation for this due to age. I have tried 2 different S= SD's and 2 different spinners. The secondary machine does not have py27-salt installed, months without panic. Install py27-salt and it starts panicking. --=20 You are receiving this mail because: You are on the CC list for the bug.=
