Hi, All. I don't have this problem, but i saw it in several users reports. System can't detect some devices. Last example (from one report): Windows/Linux detected LSI MegaRAID SAS 8408E RAID Controller on an motherboard, but freebsd didn't detect. pciconf list: hostb0@pci0:0:0:0: class=0x060000 card=0x83361033 chip=0x25d88086 rev=0xb1 hdr=0x00 pcib1@pci0:0:2:0: class=0x060400 card=0x00000000 chip=0x25f78086 rev=0xb1 hdr=0x01 pcib8@pci0:0:3:0: class=0x060400 card=0x00000000 chip=0x25e38086 rev=0xb1 hdr=0x01 pcib9@pci0:0:4:0: class=0x060400 card=0x00000000 chip=0x25f88086 rev=0xb1 hdr=0x01 pcib10@pci0:0:5:0: class=0x060400 card=0x00000000 chip=0x25e58086 rev=0xb1 hdr=0x01 pcib11@pci0:0:6:0: class=0x060400 card=0x00000000 chip=0x25e68086 rev=0xb1 hdr=0x01 pcib12@pci0:0:7:0: class=0x060400 card=0x00000000 chip=0x25e78086 rev=0xb1 hdr=0x01 hostb1@pci0:0:16:0: class=0x060000 card=0x83361033 chip=0x25f08086 rev=0xb1 hdr=0x00 hostb2@pci0:0:16:1: class=0x060000 card=0x83361033 chip=0x25f08086 rev=0xb1 hdr=0x00 hostb3@pci0:0:16:2: class=0x060000 card=0x83361033 chip=0x25f08086 rev=0xb1 hdr=0x00 hostb4@pci0:0:17:0: class=0x060000 card=0x83361033 chip=0x25f18086 rev=0xb1 hdr=0x00 hostb5@pci0:0:19:0: class=0x060000 card=0x83361033 chip=0x25f38086 rev=0xb1 hdr=0x00 hostb6@pci0:0:21:0: class=0x060000 card=0x83361033 chip=0x25f58086 rev=0xb1 hdr=0x00 hostb7@pci0:0:22:0: class=0x060000 card=0x83361033 chip=0x25f68086 rev=0xb1 hdr=0x00 pcib13@pci0:0:28:0: class=0x060400 card=0x83361033 chip=0x26908086 rev=0x09 hdr=0x01 uhci0@pci0:0:29:0: class=0x0c0300 card=0x83361033 chip=0x26888086 rev=0x09 hdr=0x00 uhci1@pci0:0:29:1: class=0x0c0300 card=0x83361033 chip=0x26898086 rev=0x09 hdr=0x00 uhci2@pci0:0:29:2: class=0x0c0300 card=0x83361033 chip=0x268a8086 rev=0x09 hdr=0x00 uhci3@pci0:0:29:3: class=0x0c0300 card=0x83361033 chip=0x268b8086 rev=0x09 hdr=0x00 ehci0@pci0:0:29:7: class=0x0c0320 card=0x83361033 chip=0x268c8086 rev=0x09 hdr=0x00 pcib14@pci0:0:30:0: class=0x060401 card=0x83361033 chip=0x244e8086 rev=0xd9 hdr=0x01 isab0@pci0:0:31:0: class=0x060100 card=0x83361033 chip=0x26708086 rev=0x09 hdr=0x00 atapci0@pci0:0:31:1: class=0x01018a card=0x83361033 chip=0x269e8086 rev=0x09 hdr=0x00 none0@pci0:0:31:3: class=0x0c0500 card=0x83361033 chip=0x269b8086 rev=0x09 hdr=0x00 pcib2@pci0:1:0:0: class=0x060400 card=0x83361033 chip=0x35008086 rev=0x01 hdr=0x01 pcib7@pci0:1:0:3: class=0x060400 card=0x83361033 chip=0x350c8086 rev=0x01 hdr=0x01 pcib3@pci0:2:0:0: class=0x060400 card=0x83361033 chip=0x35108086 rev=0x01 hdr=0x01 pcib6@pci0:2:2:0: class=0x060400 card=0x83361033 chip=0x35188086 rev=0x01 hdr=0x01 pcib4@pci0:3:0:0: class=0x060400 card=0x00000000 chip=0x03708086 rev=0x00 hdr=0x01 pcib5@pci0:3:0:2: class=0x060400 card=0x00000000 chip=0x03728086 rev=0x00 hdr=0x01 em0@pci0:12:0:0: class=0x020000 card=0x83361033 chip=0x10968086 rev=0x01 hdr=0x00 em1@pci0:12:0:1: class=0x020000 card=0x83361033 chip=0x10968086 rev=0x01 hdr=0x00 mpt0@pci0:13:5:0: class=0x010000 card=0x83361033 chip=0x00541000 rev=0x01 hdr=0x00 vgapci0@pci0:36:0:0: class=0x030000 card=0x83361033 chip=0x0522102b rev=0x02 hdr=0x00 Windows detects it as Device Description LSI MegaRAID SAS 8408E RAID Controller Bus Type PCI-X Bus / Device / Function 4 / 14 / 0 Device ID 1000-0411 Subsystem ID 1000-1001 Device Class 0104 (RAID Controller) Revision 00 Fast Back-to-Back Transactions Not Supported Device Features 66 MHz Operation Supported Bus Mastering Enabled PCI-X Device Properties 64-bit Device Yes 133 MHz Operation Supported PCI-X 266 Not Supported PCI-X 533 Not Supported --------------------------------------- So, question is why freebsd can't detect this device? -- WBR, Andrey V.
