Re: Small System Paging Problem - OOM-killer goes nuts

It seems  oom happenes when VM(page frame reclaim) try to reclaim much

disk related driver: scsi_mod, usb mass storage, usbcore and uhci or
ehci )

As far as I can tell, the problem arises because usb-storage's kernel
thread does not run with PF_MEMALLOC and cannot dip into the reserves.
