Greetings, I am running a 3ware 9500 SATA raid card in a 12x300GB raid 50 configuration. Too often, I am seeing reboots during high I/O (rsync) operations. drue@leopard:~$ uname -a FreeBSD leopard.claimlynx.com 5.4-SECURITY FreeBSD 5.4-SECURITY #0: Thu Jun 30 02:25:52 UTC 2005 root@builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC i386 This is logged in /var/log/messages just before the reboot: Oct 1 23:15:49 leopard kernel: twa0: Missing expected status bit(s) 2000<MC_RDY> Oct 1 23:15:49 leopard kernel: twa0: SCSI cmd = 0x2a: ERROR: (0x03:0x0001) Oct 1 23:15:49 leopard last message repeated 239 times Oct 1 23:15:50 leopard kernel: a: ERROR: (0x03: 0x0001) Oct 1 23:15:50 leopard kernel: twa0: SCSI cmd = 0x2a: ERROR: (0x03:0x0001) Here is dmesg identifying the controller: 3ware device driver for 9000 series storage controllers, version: 2.50.02.012 twa0: <3ware 9000 series Storage Controller> port 0xb800-0xb8ff mem 0xfb800000-0xfbffffff,0xfc5ffc00-0xfc5ffcff irq 24 at device 2.0 on pci2 twa0: 12 ports, Firmware FE9X 2.06.00.009, BIOS BE9X 2.03.01.051 Is this somethign that has been worked on in 5-STABLE or 6? Would a kernel dump be helpful? Please aim me at the appropriate list or people that would know. Thanks, Dan
