SL users,

we encountered a hung kernel with SL6, believe it is
likely a real bug with dm code running snapshots.

    sata_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.

  - since this is an "old" kernel relative to upstream,
    doubtful that linux-kernel cares

  - since this is not a "vendor" kernel i.e.  paid
    rhel6, 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.

Thanks.
