>Description: If I load ahci then I'm not able anymore to use the dvd device in my Sony Vaio laptop. But if I leave a dvd medium in the drive while booting then I get /dev/cd0. If I don't leave a medium in the drive, I have to wait about 10 seconds to get some error: ahcich1: Timeout on slot 0 ahcich1: is 00000000 cs 00000000 ss 00000000 rs 00000001 tfd 50 serr 00000000 run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config ahcich1: Timeout on slot 0 ahcich1: is 00000000 cs 00000000 ss 00000000 rs 00000001 tfd 50 serr 00000000 Without achci I have to load smb and ichsmb to get /dev/acd0. Maybe this is of some help: http://patchwork.ozlabs.org/patch/48596/ The Linux kernel had a similar problem, the drive was dead as long as I didn't leave a medium in the drive while booting. dmesg: http://bsdpaste.bsdgroup.de/54343 device: <PIONEER DVD-RW DVRTD08 1.00> at scbus2 target 0 lun 0 (pass1,cd0) pass1: <PIONEER DVD-RW DVRTD08 1.00> ATAPI-7 SATA 1.x device pass1: 150.000MB/s transfers (SATA 1.x, UDMA2, ATAPI 12bytes, PIO 8192bytes) protocol ATA/ATAPI-7 SATA 1.x device model PIONEER DVD-RW DVRTD08 firmware revision 1.00 serial number cylinders 0 heads 0 sectors/track 0 sector size logical 512, physical 512, offset 0 LBA supported LBA48 not supported PIO supported PIO4 DMA supported WDMA2 UDMA2 Feature Support Enabled Value Vendor read ahead no no write cache no no flush cache no no overlap no Tagged Command Queuing (TCQ) no no Native Command Queuing (NCQ) no SMART no no microcode download no no security no no power management yes yes advanced power management no no automatic acoustic management no no media status notification no no power-up in Standby no no write-read-verify no no unload no no free-fall no no data set management (TRIM) no >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
