I then tried rebooting 2.5.27-rmap-slablru with /home mounted as ext3, and immediately after starting dbench 1, I got this message about 10 times or so: ENOMEM in do_get_write_access, retrying. And the box was locked up. Next time, I'll have CONFIG_MAGIC_SYSRQ=y. Meanwhile, it is running the dbench 1 to 64 series under 2.4.19-rc3 with no problems at all.
