Here's what I found in recent tests on my Quadra 630.

The usual stress-ng panic can happen without list corruption, even with
local_irq_save/restore() added to do_IRQ().

The panic did not show up at all during stress tests with Al's signal
handling patch series.

I think my results are consistent with yours.

The kernel's 'memtest' didn't detect any bad DRAM but it isn't
particularly thorough so I'm running some tests with memtester-4.5.1.
