I'm suspecting the buffer cache changes to be the real problem.
Yes this is known, quick easy fix for this is to increase magic constant in free_area_init() initial comparison to 48, like so:
/* * select nr of pages we try to keep free for important stuff * with a minimum of 48 pages. This is totally arbitrary */ i = (end_mem - PAGE_OFFSET) >> (PAGE_SHIFT+7); if (i < 48) i = 48;
This is what Linus and myself have in our trees.
