https://bugzilla.kernel.org/show_bug.cgi?id=217599 --- Comment #47 from Sagar (sagar.biradar@xxxxxxxxxxxxx) --- Hi Joop, Maxim et all, I have been trying to duplicate this issue on two different machines with 2 CPUs and little luck. I was curious to know the magic ingredient that is missing in the setup. I have series-7 controllers on both machines, 3 drives attached to both the controllers, with four Raid-5 arrays created on these drives. I am running fio on all the arrays (/dev/sdb to /dev/sde). Could you share the details of tool (or any script?) that is being run on the system when you see the issue? I am mentioning both the configs here, for your reference, and please let me know if something seems conspicuous to you. Also it would really help me if you give similar details other than what has already been mentioned. Thanks Sagar Config-1 Details System Information Manufacturer: Supermicro Product Name: SYS-220U-TNR Version: 0123456789 Serial Number: S411795X2826083 BIOS Information Vendor: American Megatrends International, LLC.
