Comment 2 Marty Wesley 2005-05-26 02:38:26 EDT
PM ACK for U2.
Comment 6 Tim Burke 2005-06-15 22:22:58 EDT
eng mgt ack for inclusion on canfix list for u2, not the mustfix list.
also I agree w/ QA that there is also the expectation that Fujitsu has an
accompanying testplan and intend to perform that testing.  Note the above status
indicates this is questionable whether it will be completed in U2 or whether it
will realistically have to wait till U3 for delivery.

Also note, that this level of change must be completed by June 20th.  Reason
being we can't take in large features late in the cycle.
Comment 7 Brian Stevens 2005-06-15 22:50:02 EDT
How complete is the prototype?
Comment 9 Nobuhiro Tachino 2005-06-16 02:48:29 EDT
The kernel part is almost complete and works with no problem.
The userland part has just made and has rouge edges It needs more
internal test and review.
Comment 10 Tatsuo Uchida 2005-06-20 17:29:28 EDT
(2005-06-17) The patch is posted to rhkernel-list.
Comment 16 Nobuhiro Tachino 2005-09-21 09:24:41 EDT
I tested the U2 kernel on our machined and confirmed this feature works without
any problem.
Comment 17 Eric Hagberg 2005-09-21 13:35:45 EDT
I see problems.

Did you actually have data written out in your swap partition before causing the
crash? In my testing, this will fail - the crash won't happen because the
diskdump  signature gets overwritten when data is swapped out.
Comment 18 Eric Hagberg 2005-09-21 16:25:02 EDT
Apparently the problem was that I followed the instructions in the README,
rather than just adding my swap device to the /etc/sysconfig/diskdump file and
starting the diskdump service. Looks to be working fine now.
Comment 19 Keiichiro Tokunaga 2005-09-21 18:10:45 EDT
I will update the README and it will be in the next update of diskdumputils 
package.  Thank you for the feedback.
