Same thing.
The boot succeed if I set CONFIG_CRITICAL_IRQSOFF_TIMING to no.
If I set this parameter to yes, I get the scsi unresolved symbols.
PERCPU_ENOUGH_ROOM is actually set to 256K.
I'll try to set the original value.
I don't see the relation between this parameter and the missing scsi symbols resolution.
Timing problem ?
