Subject: oops when copying a file from a nfs mount
Date: Fri, 03 Feb 2012 23:36:04 +0100 [thread overview]
Message-ID: <20120203223604.98C91405DC@mail.chillheid.nl> (raw)
Hi,
Since updating from kernel 3.2.1 to 3.2.2, copying a file from a nfs mount
using `cp` results in a kernel oops. Copying the same file with `cat
/nfsmount/file > /local/file` gives no problems.
I can reliably trigger the oops with a simple:
cp /nfsmount/file /local/dir
