The new system is running 2.6.3-16 (from our mdk distro). We have noticed about once a day the system wedges. Today we got some debugging info in dmesg. I cannot list all processes (only some then it wedges), I can't kill many processes (they never die), and I cannot reboot. A hardware reset is required. We are using XFS on an MD stripe containing 6 disks. Some directories on the this filesystem cause ls to wedge when run on them. If it matters, yes we have 1000bt cards that we do a lot of NFS traffic over, but no special settings for large frames have been activated. I saw a similar thread from earlier this year suggesting I increase /proc/sys/vm/min_free_kbytes, which I did to no avail. Any insight is appreciated. pdflush: page allocation failure. order:0, mode:0x20 Call Trace:[] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 []=20 pdflush: page allocation failure. order:0, mode:0x20 Call Trace:[] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] [] []=20 [] []=20 --=20 Richard F.
