https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233395 --- Comment #1 from Steevan <steevanxperia@gmail.com> --- I tried contacting SuperMicro and then Intel tech support. Both suggested t= hat the issue could be specific to FreeBSD OS.=20 So later I tried FreeBSD 12 Beta 3 version on this server with Xeon Gold 5= 115 CPU. All these problems have disappeared. In this FreeBSD 12 Beta3 also contigf= ree takes much more time compared to contigmalloc.=20 However when I compare the absolute values to FreeBSD 11.x number I can see huge improvement in FreeBSD 12 Beta 3. Now in FreeBSD 12 Beta3 my PCIe card driver takes just a few seconds to load and few seconds to unload.=20 However on FreeBSD 11.x it takes 2+ minutes to load and upto 15 minutes to unload.=20 Hence it looks like the problem is with FreeBSD 11.x.=20 Hope the attached simple program in original bug report helps you guys to reproduce this issue.=20 Best Regards, Steevan --=20 You are receiving this mail because: You are the assignee for the bug.=
