[PATCH 0/7] Patches for kdump vs. INIT

seto.hidetoshi@xxxxxxxxxxxxxx (Hidetoshi Seto) · Thu, 18 Jun 2009 15:44:23 +0900

Hi Tony-san, and kdump folks,

I got some trouble on kdump on IPF with INIT, and my investigation
proves there are some bugs and races in startup of kdump.
Here are fixes based on .30, for issues I found.

Since it must be serious problem for (likely big) IPF servers if we
could fail to retrieve crashdump via kdump, so I believe these patches
should be applied asap.

Thanks,
H.Seto
