Title:
4.15.0 memory allocation issue
Status in linux package in Ubuntu:
Confirmed
Bug description:
My server is :
PowerEdge T630
2x Intel(R) Xeon(R) CPU E5-2623 v4 @ 2.60GHz
128G of ram
4x VGA compatible controller [0300]: NVIDIA Corporation GP102 [TITAN X]
[10de:1b00] (rev a1)
Starting 116G ram 16vcpus + 4 pci passthrough allocating memory stops
after about half of the memory.
When upgrading from kernel 4.13.0 to 4.15.0 starting a vm takes a long
time.
I tested kernel :
linux-image-4.13.0-37 not affected
linux-image-4.13.0-45 not affected
linux-image-4.15.0-34 affected
linux-image-4.15.0-42 affected
After disabling transparent_hugepage on 4.15 everything seems to work
correctly.
cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.15.0-42-generic root=UUID=<some uuid> ro
intel_iommu=on transparent_hugepage=never splash quiet vt.handoff=7
