Hi, I'm in the process of updating a machine to 9-STABLE from a week or two ago. When compiling masses of ports something never seen before happens: Oct 19 11:54:26 puma kernel: ahcich3: Timeout on slot 28 port 0 Oct 19 11:54:26 puma kernel: ahcich3: is 00000008 cs 00000000 ss 00000000 rs ffffffff tfd 50 serr 00000000 cmd 00007c17 Oct 19 11:54:26 puma kernel: (ada1:ahcich3:0:0:0): WRITE_FPDMA_QUEUED. ACB: 61 40 7f 6b aa 40 09 00 00 00 00 00 Oct 19 11:54:26 puma kernel: (ada1:ahcich3:0:0:0): CAM status: Command timeout Oct 19 11:54:26 puma kernel: (ada1:ahcich3:0:0:0): Retrying command And another one: Oct 18 15:16:20 puma kernel: ahcich3: Timeout on slot 19 port 0 Oct 18 15:16:20 puma kernel: ahcich3: is 00000008 cs 00000000 ss 00000000 rs ffffffff tfd 50 serr 00000000 cmd 00007317 Oct 18 15:16:20 puma kernel: (ada1:ahcich3:0:0:0): WRITE_FPDMA_QUEUED. ACB: 61 08 df c6 5d 40 11 00 00 00 00 00 Oct 18 15:16:21 puma kernel: (ada1:ahcich3:0:0:0): CAM status: Command timeout Oct 18 15:16:21 puma kernel: (ada1:ahcich3:0:0:0): Retrying command These are the two occurances I saw running through on the console, there may be more. The disk is one of those funny things getting active when idle after writing big files to it: ada1: <TOSHIBA DT01ACA200 MX4OABB0> ATA8-ACS SATA 3.x device ahci1: <AMD SB7x0/SB8x0/SB9x0 AHCI SATA controller> port 0xb000-0xb007,0xa000-0xa003,0x9000-0x9007,0x8000-0x8003,0x7000-0x700f mem 0xfe4ffc00-0xfe4fffff irq 19 at device 17.0 on pci0 ahci1: AHCI v1.20 with 4 6Gbps ports, Port Multiplier supported ahcich2: <AHCI channel> at channel 0 on ahci1 ahcich3: <AHCI channel> at channel 1 on ahci1 ahcich4: <AHCI channel> at channel 2 on ahci1 ahcich5: <AHCI channel> at channel 3 on ahci1 What is happening there and why? Do I need to worry? TIA, Marc -- Marc Santhoff <M.Santhoff@web.de>
