SL users,
we encountered a hung kernel with SL6, believe it is
likely a real bug with dm code running snapshots.
=A0 =A0sata_sil24 -> md raid5 -> dm snapshot -> ext4 jbd -> hung IO
checked whole site sl.org and most documents there, but
found no information on how to report bugs.
=A0- since this is an "old" kernel relative to upstream,
=A0 =A0doubtful that linux-kernel cares
=A0- since this is not a "vendor" kernel i.e. =A0paid
=A0 =A0rhel6, doubt redhat cares
thus, not sure of the appropriate bug reporting method.
I have tons of debug info... able to capture copious
sysrq-induced dumps from serial console.
Please advise on the appropriate procedure for
reporting these kinds of kernel bugs.
I would recommend you file a bugzilla at https://bugzilla.redhat.com
even if you are not a customer. This is a bug report, not a support
request. We contribute upstream by reporting bugs. :-)
But do not reference Scientific Linux .

Speaking of a sata_sil-related bug, there used to be one as seen in
this CentOS bug tracker:
http://bugs.centos.org/view.php?id=3D3165
The CentOSPlus kernel had a fix for it for years until it was
eventually fixed upstream:
https://bugzilla.redhat.com/show_bug.cgi?id=3D640586
