David, you don't appear to have a bugzilla account. This appears to be the same bug as http://bugzilla.kernel.org/show_bug.cgi?id=7727. Can we fix it please? Sascha, is this repeatable?

And when I'm trying to make a local backup (using tar -czf to an local disk) this produces the oops too. So, I think this is somehow connected to IO. -Sascha Reply-To: dhowells@redhat.com Andrew Morton <akpm@osdl.org> wrote: > This bug is in the keyring management code, not the IO scheduler. > > David, you don't appear to have a bugzilla account. No, it seems not. I'll have a look at the bug anyway. I'm sure it's also got a Fedora BZ #, but I can't seem to find it. David David, Can you confirm that fix to http://bugzilla.kernel.org/show_bug.cgi?id=7727 also applies to this bug? Thanks, --Natalie |
