>From what I can ascertain the "SONY DVD DW-D26A" is not a SONY drive. It >appears to be a re-badged Lite-On SOHW-1673S. See here for more details: http://www.linuxquestions.org/hcl/showproduct.php?product=3441&cat=all
One previous person also reported this problem with a Lite-On drive but no model ID was supplied (see Bogolisk 2007-07-24 above). The diagnostic error message reported is consistent with this bug: hdd: DMA timeout retry hdd: timeout waiting for DMA hdd: status timeout: status=0xd0 { Busy } ide: failed opcode was: unknown hdd: drive not ready for command So, yes, it does seem that there may be some Lite-On drives experiencing this problem. A comparison of kernel logs for the bug between Lite-On & TSSTcorp would be interesting. This Lite-On drive appears to have caused problems for both Linux & MSWindows systems. A quick web search shows that numerous MSWindows users have had trouble with the Lite-On SOHW-1673S (very high failure rate when burning DVDs). Firmware upgrade is widely reported as the solution for MSWindows users. Firmwares JYS2 & possibly a JYS3 are available (see here: http://forum.rpc1.org/dl_firmware.php?download_id=2081 Some other drives that may have trouble (very few reports) TSSTcorp CD/DVDW SH-S183L [bug with SB01 : SB02 (28/6/07) is available from Samsung] TSSTcorp CD/DVDW SN-S082D [SS03 (4/3/07) firmware upgrade fixed bug - note:there are two (csel=high or low) firmwares for this drive] TSSTcorp CD/DVDW TS-H552B [TS12 seems to be latest in long line of firmware upgrades] However, almost all reported drives exhibiting this problem are TSSTcorpCD/DVD TS-L632D optical drives. Also note that this bug commentary is not the only report of this or similar bugs with the TSSTcorpCD/DVD TS-L632D. Bug #75295 mostly reports on the bug concerning IDE connections Bug #84603 mostly concerns PCs with SATA connections Bug #117441 concerns System76 PCs. Nearly all reported optical drive models in the above three listed bugs (and their included duplicate bugs) are TSSTcorpCD/DVD TS-L632D. Furthermore, all those with TS-L632D who have done a firmware upgrade to SC03 or SC04 have reported that it fixed the bug. -- Feisty freeze, kernel (?) tries to access DVD drive https://bugs.launchpad.net/bugs/75295 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
