Today I put in a new disk to switch to full raid5 mode. Shortly after the command raidhotadd the system crashed with the message lost interrupt on cpu1. This continued after reboot. I finaly managed to get it running again by booting with kernel parameter maxcpus=1. In this one CPU mode it finished resycing. During this process I was never able to resync with two CPU's. After finishing rescyncing the system run now fine in SMP Dual mode again. Perhaps there might be an issue with spinlocks during resyncing. Bye Otto
