Thanks for the pointers. I'm afraid I can't see anything that looks like the setting I need to change... I'm using Compaq SmartArray 221 rev 4.16, if that sheds any light. BTW, the previous attempts did at least get as far as checking the number INTs on the system, and the number was exactly 37. If there were fewer than that provided for in the kernel, it froze even quicker than the current SMP kernel! Any further hints would be most gratefully (even greedily) received!
