Try turning off gdb if it is compiled into the kernel. I've been having random signal-induction problems with old QLogic 1041 adapters since about 4.0 or so. It was the changes to have more than 32 signals that seemed to start the problem. I get random SIGTERM, SIGPROFILE and other signals, usually 'profiling timer expired' if the system is lucky enough to actually boot all the way. Sometimes it is an fsck or other somewhat lengthy startup process that is the first to die. I finally found that removing gdb from the kernel made the problem dissapear, or at least less severe, but I also now have to statically compile in the ispfw device to load firmware early in the boot, otherwise it still often dies, even with no gdb, before loading the firmware, but that may be related more to the incredibly old firmware on the controllers. The problem seems significantly more severe on SMP-hardwared boxen. Let me know if you need more info, as I'd be glad to help. I have more than 10 1041 HBAs.
