Ingo,
*** Warning: "__you_cannot_kmalloc_that_much" [drivers/scsi/aacraid/aacraid.ko] undefined!
This just appeared in U5. I was trying to track this one down just
because I saw it, even though I don't need aacraid. I am having a hell
of a time tracking down what changed that would cause this, but I
figure you will know exactly what changed that would cause it. :)
i suspect this is due to the size increase of semaphores if
CONFIG_RWSEM_DEADLOCK_DETECT is enabled. Try lowering
CONFIG_RWSEM_MAX_OWNERS from the default 64 to 32, does that help?
