Hello! I'm running kernel 2.6.26.5 no patches and came across this after installing a new DVD drive. This is a Samsung SN-S083A slimline optical connected with SATA cable to VIA EPIA EX15000 motherboard. I get the exception trying a blank command such as "wodim dev=0,1,0 blank=fast". HDD and DVD are detectable only with pata_via, this seems strange as they are SATA drives connected with SATA cable. I have tried both AHCI and sata_via, leaving out pata_via, but that always ends up in kernelpanic and unbootable root filesystem. I assume no drives were found (kernel text scrolls too fast to read). When the DVD fails it seems to drag the HDD with it. Eventually the HDD comes back but after that the DVD is nowhere to be found. I am unsure what I can do to fix this issue but changing kernel is definately an option if that helps. syslog: Oct 13 20:51:56 silverstone kernel: ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen Oct 13 20:51:56 silverstone kernel: ata1.01: cmd a0/00:00:00:00:00/00:00:00:00:00/b0 tag 0 Oct 13 20:51:56 silverstone kernel: cdb 54 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Oct 13 20:51:56 silverstone kernel: res 40/00:02:00:4c:00/00:00:00:00:00/b0 Emask 0x4 (timeout) Oct 13 20:51:56 silverstone kernel: ata1.01: status: { DRDY } Oct 13 20:51:56 silverstone kernel: ata1: soft resetting link Oct 13 20:51:56 silverstone kernel: ata1.01: qc timeout (cmd 0xa1) Oct 13 20:51:56 silverstone kernel: ata1.01: failed to IDENTIFY (I/O error, err_mask=0x4) Oct 13 20:51:56 silverstone kernel: ata1.01: revalidation failed (errno=-5) Oct 13 20:51:56 silverstone kernel: ata1: failed to recover some devices, retrying in 5 secs Oct 13 20:51:56 silverstone kernel: ata1: link is slow to respond, please be patient (ready=0) Oct 13 20:51:56 silverstone kernel: ata1: device not ready (errno=-16), forcing hardreset Oct 13 20:51:56 silverstone kernel: ata1: soft resetting link Oct 13 20:51:56 silverstone kernel: ata1.01: qc timeout (cmd 0xa1) Oct 13 20:51:56 silverstone kernel: ata1.01: failed to IDENTIFY (I/O error, err_mask=0x4) Oct 13 20:51:56 silverstone kernel: ata1.01: revalidation failed (errno=-5) Oct 13 20:51:56 silverstone kernel: ata1: failed to recover some devices, retrying in 5 secs Oct 13 20:51:56 silverstone kernel: ata1: link is slow to respond, please be patient (ready=0) Oct 13 20:51:56 silverstone kernel: ata1: device not ready (errno=-16), forcing hardreset Oct 13 20:51:56 silverstone kernel: ata1: soft resetting link Oct 13 20:51:56 silverstone kernel: ata1.01: qc timeout (cmd 0xa1) Oct 13 20:51:56 silverstone kernel: ata1.01: failed to IDENTIFY (I/O error, err_mask=0x4) Oct 13 20:51:56 silverstone kernel: ata1.01: revalidation failed (errno=-5) Oct 13 20:51:56 silverstone kernel: ata1.01: disabled Oct 13 20:51:56 silverstone kernel: ata1.00: failed to IDENTIFY (I/O error, err_mask=0x40) Oct 13 20:51:56 silverstone kernel: ata1.00: revalidation failed (errno=-5) Oct 13 20:51:56 silverstone kernel: ata1: failed to recover some devices, retrying in 5 secs Oct 13 20:51:56 silverstone kernel: ata1: link is slow to respond, please be patient (ready=0) Oct 13 20:51:56 silverstone kernel: ata1: device not ready (errno=-16), forcing hardreset Oct 13 20:51:56 silverstone kernel: ata1: soft resetting link Oct 13 20:51:56 silverstone kernel: ata1.00: configured for UDMA/133 Oct 13 20:51:56 silverstone kernel: ata1: EH complete Oct 13 20:51:56 silverstone kernel: sd 0:0:0:0: [sda] 976773168 512-byte hardware sectors (500108 MB) Oct 13 20:51:56 silverstone kernel: sd 0:0:0:0: [sda] Write Protect is off Oct 13 20:51:56 silverstone kernel: sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 Oct 13 20:51:56 silverstone kernel: sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA hdparm -I /dev/sr0: /dev/sr0: ATAPI CD-ROM, with removable media Model Number: TSSTcorp CDDVDW SN-S083A Serial Number: Firmware Revision: SB01 Standards: Supported: CD-ROM ATAPI-3 -4 -5 -6 -7 Configuration: DRQ response: 50us.
