Hi Neil, That solution would be very specific to RedHat. If a user on non RHEL5 distro tries to use kdump then how would he handle it? Another option can be that we specify this thing in kdump documentation so that a user can add this parameter additionally along with maxcpus=1 and irqpoll. Then respective distros can choose to automate this whole process and add append reset_devices through init scripts. What do other think about it?
