This doesn't seem to occur with a 20090315 snapshot so _maybe_ its related to this commit: mav 2009-03-30 22:18:38 UTC FreeBSD src repository Modified files: sys/dev/ata ata-pci.c ata-pci.h ata-sata.c sys/dev/ata/chipsets ata-ahci.c ata-intel.c ata-jmicron.c ata-marvell.c ata-nvidia.c ata-promise.c ata-siliconimage.c ata-sis.c ata-via.c Log: SVN rev 190581 on 2009-03-30 22:18:38Z by mav Integrate user/mav/ata branch: Add ch_suspend/ch_resume methods for PCI controllers and implement them for AHCI. Refactor AHCI channel initialization according to it. Fix Port Multipliers operation. It is far from perfect yet, but works now. Tested with JMicron JMB363 AHCI + SiI 3726 PMP pair. Previous version was also tested with SiI 4726 PMP. Hardware sponsored by: Vitsch Electronics / VEHosting.nl (I first tried manually reverting commit 191568 in the 20090623 kernel as this box has an amd/ati sb600, but that seemed to make no difference.) While doing that I discovered another problem tho: I installed onto an usb key for testing, and booting that panic'd in tdq_notify+0x4e with a trap due to a null pointer here: movzbl 0x27a(%rax),%edx (it was trying to read from 0x27a; the backtrace was almost empty as this seems to be part of the scheduler - I can post the backtrace too if anyone's interested.) I then got it to boot into single user, and from there got into multiuser, and then discovered the ata issue... The good news is the new usb stack seems to like my printer better! (I didn't actually test printing itself but at least it got detected at boot, which on 7-stable it doesn't, I always have to plug it into another port atm after boot before I can use it...) Ok that should be enough for now. Cheers, :) Juergen PS: ata5 related parts of stable dmesg: ... ata5: <ATA channel 3> on atapci0 ata5: SATA connect time=0ms ata5: SIGNATURE: eb140101 ata5: ahci_reset devices=0x4<ATAPI_MASTER> ata5: [MPSAFE] ata5: [ITHREAD] ... ata5-master: pio=PIO4 wdma=WDMA2 udma=UDMA100 cable=40 wire ata5: device_reset timeout=660us acd1: <ATAPI BD B DH4B1S/7P5B> DVDR drive at ata5 as master acd1: read 5512KB/s (5512KB/s) write 5512KB/s (5512KB/s), 16384KB buffer, SATA150 acd1: Reads: CDR, CDRW, CDDA stream, DVDROM, DVDR, packet acd1: Writes: CDR, CDRW, DVDR, test write, burnproof acd1: Audio: play, 2 volume levels acd1: Mechanism: ejectable tray, unlocked acd1: Medium: no/blank disc ... ...and the other optical drive that also gets detected on head (this dmesg still from stable:) ... ata3: <ATA channel 1> on atapci0 ata3: SATA connect time=0ms ata3: SIGNATURE: eb140101 ata3: ahci_reset devices=0x4<ATAPI_MASTER> ata3: [MPSAFE] ata3: [ITHREAD] ... ata3-master: pio=PIO4 wdma=WDMA2 udma=UDMA66 cable=40 wire ata3: device_reset timeout=120us acd0: <PIONEER DVD-RW DVR-216D/1.09> DVDR drive at ata3 as master acd0: read 6890KB/s (6890KB/s) write 5511KB/s (6890KB/s), 2000KB buffer, SATA150 acd0: Reads: CDR, CDRW, CDDA stream, DVDROM, DVDR, DVDRAM, packet acd0: Writes: CDR, CDRW, DVDR, test write, burnproof acd0: Audio: play, 256 volume levels acd0: Mechanism: ejectable tray, unlocked acd0: Medium: no/blank disc ... ..so maybe (wild guess!)
