https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D196944 --- Comment #2 from Andrew Daugherity <andrew.daugherity@gmail.com> --- I've found the commit that breaks it: base r241438 (which was MFC into stab= le/9 as 243546). Reading the commit history between 9.1 and 9.2, I saw that r24= 8226 (MFC onto 9-stable as r248858) claims to fix IPMI on a Sun X2200 that broke with 241838, so my first test was to see if it was working just before that. I built a 9.2 kernel with sys/dev/bge/if_bge.c rolled back to the commit be= fore the "bad" one, 243541 (MFC from 241436), and IPMI works! (I did not touch = any other files.) Also works for a stable/9 kernel (identified as 9.3-STABLE #1 r243541:295788) with if_bge.c at 243541. If I update if_bge.c to the commit in question (241438 aka 243546), IPMI is broken once more. I also tried r248858 (248226) which supposedly fixed IPM= I on those Sun servers but it did not help here. I have not tried any other commits, as it appears that for my hardware, it works on <=3D241436 and is = broken for >=3D241438. I also fixed my 10.2 kernel in the same way by rolling back if_bge.c to r241436. I had to merge r242426 and r242625 to get it to build; after doin= g so IPMI works in 10.2! Obviously rolling all the way back like this isn't the solution for everyon= e, as there have been many other commits since then, but at least I found the breakage point. I don't know the bge driver or kernel well enough to prope= rly fix it, but hopefully this is good information for someone who does. --=20 You are receiving this mail because: You are the assignee for the bug.=
