Can someone please explain what it= =20 > means? With Thanks, It means that the disk has processed the write request (interrupt seen), = but that the system (the bio_taskqueue) hasn't been able to get the=20 result returned to the kernel. Your disk is not involved in this problem since it has done its part,=20 but the rest of the system is either busy with something else, or there=20 are bugs lurking that prohibits the bio_taskqueue from running. Either way its a WARNING not a FAILURE :) --=20 -S=F8ren
