Subject: 2.6.4 OOPS in nfsd (repeatable)
Date: Fri, 12 Mar 2004 22:35:40 -0800 [thread overview]
Message-ID: <20040313063540.GA882@defiant.tbdnetworks.com> (raw)
Hi,
the OOPS I reported for 2.6.4-rc1-bk3 is still in 2.6.4.
To trigger it, I mount a ext3 FS from a Solaris 5.7 machine using
-o proto=tcp,vers=3 and then run a "find /mnt | wc -l" on the Sun against a
directory containing about 4000 files.
Mounting with -o proto=tcp,vers=2 works fine.
Linux version 2.6.4 (nkiesel@defiant) (gcc version 3.3.3 (Debian 20040306)) #16 Thu Mar 11 01:25:25 PST 2004
CONFIG_NFS_FS=m
CONFIG_NFS_V3=y
# CONFIG_NFS_V4 is not set
# CONFIG_NFS_DIRECTIO is not set
CONFIG_NFSD=m
CONFIG_NFSD_V3=y
# CONFIG_NFSD_V4 is not set
CONFIG_NFSD_TCP=y
