This (i.e. the "kmem_map too small" message seen with kernel memory shortage) could be due to CAM CTL ('device ctl' added in 9.1), which is quite a big kernel memory consumer. Try to disable CTL in loader with kern.cam.ctl.disable=1 to finish boot. A longer term workaround could be to postpone those memory allocations until the first call to CTL. # cam ctl init allocates roughly 35 MB of kernel memory at once # three memory pools, somewhat under M_DEVBUF, and memory disk # devbuf takes 1022K with kern.cam.ctl.disable=1 Type InUse MemUse HighUse Requests Size(s) devbuf 213 20366K - 265 16,32,64,128,256,512,1024,2048,4096 ctlmem 5062 10113K - 5062 64,2048 ctlblk 200 800K - 200 4096 ramdisk 1 4096K - 1 ctlpool 532 138K - 532 16,512 -- wbr, pluknet _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
