System: FreeBSD amigo.home.pirzyk.org 5.2-CURRENT FreeBSD 5.2-CURRENT #15: Fri Jan 30 19:24:10 CST 2004 root at amigo.home.pirzyk.org:/usr/obj/usr/src/sys/AMIGO_KERNEL i386


	Install a Maxtor 200GB drive in the system:
	ad3: 194481MB <Maxtor 6Y200P0> [395136/16/63] at ata1-slave UDMA100

>Description:
	If I create a 200GB partition, the newfs hangs with the errors below.
	If I create 2 partitions and try to vinum concat them togther, I still
	get the same errors.

Feb  1 19:59:22 <kern.crit> amigo kernel: ad3: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=398283479
Feb  1 19:59:27 <kern.crit> amigo kernel: ad3: WARNING - WRITE_DMA interrupt was seen but timeout fired LBA=398283479
Feb  1 19:59:32 <kern.crit> amigo kernel: ad3: WARNING - WRITE_DMA interrupt was seen but taskqueue stalled LBA=398283479

	And the system hangs with the newfs command in [physrd] and cannot be 
	killed.

>How-To-Repeat:
	Do anything that accesses the disk past the 127GB boundry.

>Fix:

	Currently I only have a 127GB filesystem on the disk.
