Subject: 4.4-RELEASE kernel deadlock ("FFS node")
Message-ID: <20010921091928.Q7319@chips.research.att.com>

hi-
i was asked to help install 4.4-RELEASE on one of our systems here.
in order to test it, i was attempting to build a release locally
(i.e. running "make release ..." in /usr/src/release). note that
"make buildworld" worked fine. i've tried "make release" a couple of
times, but the system is unable to complete this task: the
kernel deadlocks during the cvs checkout of the ports collection.
^T shows the cvs process stuck in the "FFS node" wait state. all
other processes hang as a result of this:
... lots of output from "make release" ...
U ports/x11/qrash/files/patch-ao
U ports/x11/qrash/files/patch-ap
U ports/x11/qrash/files/patch-aq
U ports/x11/qrash/files/patch-ar
U ports/x11/qrash/files/patch-as
load: 0.00 cmd: cvs 13478 [FFS node] 15.46u 48.67s 0% 5816k
load: 0.00 cmd: cvs 13478 [FFS node] 15.46u 48.67s 0% 5816k
... system is deadlocked ...
the one unusual thing about the configuration is that the filesystem
we are attempting to build on is a 136GB ccd across 4 scsi disks with
the fsize=8192 and the bsize=65536 (it is mainly to be used for large
data log files):
# /dev/ccd0c:

e: 284531200 0 4.2BSD 8192 65536 16 # (Cyl. 0 - 138931*)
the ccd config is:
# ccd ileave flags component devices
ccd0 128 none /dev/da0e /dev/da1e /dev/da2e /dev/da3e
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ccd0e 141570472 16580216 113664624 13% /a
i've tried it with and without soft updates, and with and without
"async" mount.... it deadlocks in all modes i tried.
is this "FFS node" deadlock a known problem? any suggestions as
to how to deal with it? i'll include dmesg of the system below.
please cc me on any replies, as my connection to all BSD mailing lists
is down due to the BSD news server being located near the world trade
center in NYC.
thanks,
