First, I'd recommend trying to disable SWAP completely - it might help:
$ sudo swapoff -a
If you compile your own kernel or your distro hasn't enabled them for you, here's the list of the options you need to enable:
BLK_WBT, enable support for block device writeback throttling BLK_WBT_MQ, multiqueue writeback throttling BLK_WBT_SQ, single queue writeback throttling
They are all under "Enable the block layer".
If disabling swap and enabling these options have no effect, please ***create a new bug report*** and provide the following information:
CPU Motherboard and BIOS version RAM type and volume Storage and its type Kernel version and its .config
And also the complete output of these utilities:
dmesg lspci -vvv lshw free vmstat (when the bug is exposed)
cat /proc/interrupts cat /proc/iomem cat /proc/meminfo cat /proc/mttr
