Hi, I have a core-2 system with a 3ware SATA RAID controller for the main disks and the built-in Intel ICH9 4-port SATA controller that is only used for the DVDR. An 8-STABLE kernel csup'd and compiled on April 25 works fine on this system. Kernels from source csup'd this week are extremely unstable and usually panic or hang just minutes after booting. The following warning messages appear after the kernel probes the SATA controller and/or ICH9 USB controller and continue about once per 1-2 seconds until the system crashes: May 13 14:21:05 sonicyouth kernel: unknown: WARNING - ATAPI_IDENTIFY requeued due to channel reset LBA=0 Disabling the ICH9 SATA controller in the BIOS allows the system to boot and run normally. Changes were made on April 28 to allow better support for 6-port ICH9 controllers (SVN rev 221156) and I am wondering if my controller is now being incorrectly recognized. Here's the relevant kernel messages: May 13 13:52:53 sonicyouth kernel: atapci1: <Intel ICH9 SATA300 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x1c4 0-0x1c4f,0x1c30-0x1c3f at device 31.2 on pci0 May 13 13:52:53 sonicyouth kernel: ata0: <ATA channel 0> on atapci1 May 13 13:52:53 sonicyouth kernel: ata0: [ITHREAD] May 13 13:52:53 sonicyouth kernel: ata1: <ATA channel 1> on atapci1 May 13 13:52:53 sonicyouth kernel: ata1: [ITHREAD] May 13 13:52:53 sonicyouth kernel: atapci2: <Intel ICH9 SATA300 controller> port 0x1cb8-0x1cbf,0x1cac-0x1caf,0x1cb0-0x1cb7 ,0x1ca8-0x1cab,0x1c60-0x1c6f,0x1c50-0x1c5f irq 18 at device 31.5 on pci0 May 13 13:52:53 sonicyouth kernel: atapci2: [ITHREAD] May 13 13:52:53 sonicyouth kernel: ata3: <ATA channel 0> on atapci2 May 13 13:52:53 sonicyouth kernel: ata3: [ITHREAD] May 13 13:52:53 sonicyouth kernel: ata4: <ATA channel 1> on atapci2 May 13 13:52:53 sonicyouth kernel: ata4: [ITHREAD] If I csup the most recent kernel sources, I get the same problem. However, if, after csuping the latest kernel sources, I then fetch the version of sys/dev/ata/ata-all.c as of April 27, everything works fine.
