I am having similar lockups with 2.2.12, 2.2.13pre[8,9], etc.
The messages I typically get are:
EXT2-fs error (device sd(8,33): ext2_new_block: Free blocks count
corrupted
for block group 235 [only appears on the Dell sometimes]
and when NFS locks up I get:
nfs_dentry_delete: //xfer: ino=<some number>, count=2, nlink=2
About all I can do is get a dump with the SYSRQ keys. NFS seems
to be locked up in fs/nfs/inode.c: nfs_free_dentries()

My problem crops up when I am NFS copying 1G of files from from box A to
box B and 1G from box B to box A, all via 100-T. Then I execute the
following on either box (e.g., box A):
on box A:
cd <some dir on NFS mounted directory box B>
mkdir testfiles
cp <some files> testfiles
in a loop, do:
ln -s testfiles testfiles-1
ls testfiles*
rm testfiles-1
mv testfiles testfiles-1
ln -s testfiles-1 testfiles
ls testfiles*
rm testfiles
mv testfiles-1 testfiles
enddo
System:
Penguin dual PIII, RedHat 6.0,
Dell WS 400 dual PII/300, RedHat 6.0
both are SMP boxes with 2.2.12, 2.2.13pre8, 2.2.13pre9, and 2.2.13pre9+
Andrea's patches (almost pre10) including ikd.
I have been working with Alan Cox and Andrea Arcangeli on this issue.
If anyone has any similar lockups or other info, please share it
with us....
Cheers,
