I have a case where a soft lockup can be always reproduced.
System: HP Compaq dc5800 Microtower, Intel Core2 Duo CPU E8500 @ 3.16GHz
openSUSE 11.3 x86_64, all patches applied
Linux rhg-lx 2.6.34-12-default #1 SMP 2010-06-29 02:39:08 +0200 x86_64 x86_64
x86_64 GNU/Linux
To reproduce, a NFS mount is necessary.
1) I cd to a NFS mounted directory.
cd /some/nfs/mounted/directory
2) There, I do a recursive search for some text pattern with fgrep -r, such as:
fgrep -r 'Some Text' . >x1
As you see, by accident I write the fgrep result to a file which is located in
the same directory where I do the recursive search. This is what causes the
issue.
Note that the search pattern must match the text in at least some of the files
located below the directory where I do the recursive search, so that something
is written to the x1 file.
Almost immediately, the whole X session freezes, and after a minute a soft
lockup message is written to the syslog (attached, see nfs-soft-lockup.txt
file).
