[Bug 266951] Re: Buffer I/O error on device sr0 Logical Block XXXXXX in Intrepid Ibex Alpha 5
I have done some more testing, and as you say DVD-s work fine. My previous cdr-s were burnt with wodim 1.1.2 (debian etch) and wodim 1.1.8. This time I tried adding -dao option to wodim, and guess what, now the cds boot fine and give me no errors during mount. However, since I also experienced error with some factory made cds (not all) and also with a cd burnt with ISO recorder Powertoy in windows, then I still suspect that the cd-rom driver being the culprit. I'm not sure though, but I'm happy with the workaround for the time being. -- Buffer I/O error on device sr0 Logical Block XX in Intrepid Ibex Alpha 5 https://bugs.launchpad.net/bugs/266951 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 266951] Re: Buffer I/O error on device sr0 Logical Block XXXXXX in Intrepid Ibex Alpha 5
I did some more testing today on the SH-S203P drive. I did both a BIOS upgrade, tried to to experiment with setting SATA to compatible mode in BIOS and disabling memory remapping. Also tried to boot with acpi=off noapic nolapic nohz=off pci=nomsi settings (and a combination of those), but it didn't help. If a cd is in the drive during boot, this error occurs once the "Uniform cd-rom driver Revision: 3.20" is loaded and then it has to timeout to go further. If I try to mount a cd-rom, the error occurs at once: Nov 10 17:53:14 pluto kernel: [ 909.054544] sr 4:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK Nov 10 17:53:14 pluto kernel: [ 909.054550] sr 4:0:0:0: [sr0] Sense Key : Medium Error [current] Nov 10 17:53:14 pluto kernel: [ 909.054553] sr 4:0:0:0: [sr0] Add.

Tried with different DVDs. Yesterday I installed 8.10 server from a burnt mini iso, and although I had to wait with patience to wait for a timeout everytime the drive was accessed, the install completed. If you want me to perform any more testing, just tell me. It would be nice to get this resolved. ** Description changed: Hello everyone.

I just rebooted the computer with the Samsung SH-S183A drive, and it gives me the same medium error with the same sectors. This computer has another Asus motherboard, althoug it's Asus M2N-SLI Deluxe, so it's entirely different. Yes, this happens on different cdr-media. I find it higly unlikely that both drives are defective and that 8 cd's fail. The error is more or less like this: sr 4:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK sr 4:0:0:0: [sr0] Sense Key : Medium Error [current] Info fld=0x0 sr 4:0:0:0: [sr0] Add.

I'm experiencing the same kind of errors while trying to install Ubuntu 8.10 release. I have tried both i386 and amd64. The issue occurs during boot from the cd, and no matter what I do I get a medium error with error messages exactly as those draimus listed. I have tried differend media, different burning speed, it doesn't help. Media always burns fine, and I have no problems mounting the burnt cd-media in 8.04 and copying all the content. It's during boot that the problem arises, and it's always the same sector that's listed. I have two different Samsung drives, the one that gives med the error is SH-S203P. Tried burning a cdr i the SH-S183A, and then booting in the second one, same error same sector. I'm probably going to try a dvd-r this time, and check what happens. I find it very strange. My motherboard is Asus Formula Rampage with the X48 chipset, if it matters. Both DVD burners are SATA.
