We found in testing that certain PCI devices don't handle the kexec'ed kernel reboot gracefully on IA64 Altix. Some GbE card would get into a bad state permanently after one reboot, and resulted in MCA on the machines when booting kexec'ed kernel thereafter. The MCA was a result of a PIO read to the Expansion ROM of the card. We also saw a USB card issuing stale DMA's which was queued up prior to the kexec reboot. Do you observe similar problems on other platforms? Are the drivers supposed to reset the cards when it re-attach to the card on the kexec reboot?
