I got a similar problem, but there was a complete freeze of the desktop, after inserting a audio-cd into a scsi-cdrom (Kubuntu 6.06). restart of x-server wasn't succsessful: 006-12-22 20:56:27 asta kernel [17181783.312000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.312000] sg_write: data in/out 56/56 bytes for SCSI command 0x12--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.316000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.316000] sg_write: data in/out 22/22 bytes for SCSI command 0x1a--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.320000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.320000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.320000] sg_write: data in/out 12/12 bytes for SCSI command 0x1a--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.320000] sg_write: data in/out 56/56 bytes for SCSI command 0x12--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.324000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.324000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.324000] sg_write: data in/out 12/12 bytes for SCSI command 0x43--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.324000] sg_write: data in/out 22/22 bytes for SCSI command 0x1a--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.328000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.328000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.328000] sg_write: data in/out 12/12 bytes for SCSI command 0x1a--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.328000] sg_write: data in/out 12/12 bytes for SCSI command 0x43--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.332000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.332000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:56:27 asta kernel [17181783.332000] sg_write: data in/out 12/12 bytes for SCSI command 0x43--guessing data in; 2006-12-22 20:56:27 asta kernel [17181783.332000] sg_write: data in/out 12/12 bytes for SCSI command 0x43--guessing data in; 2006-12-22 20:57:06 asta kernel [17181821.516000] printk: 22 messages suppressed. 2006-12-22 20:57:06 asta kernel [17181821.516000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:57:06 asta kernel [17181821.516000] sg_write: data in/out 56/56 bytes for SCSI command 0x12--guessing data in; 2006-12-22 20:57:06 asta kernel [17181821.520000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:57:06 asta kernel [17181821.520000] sg_write: data in/out 22/22 bytes for SCSI command 0x1a--guessing data in; 2006-12-22 20:57:06 asta kernel [17181821.524000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:57:06 asta kernel [17181821.524000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:57:06 asta kernel [17181821.524000] sg_write: data in/out 12/12 bytes for SCSI command 0x1a--guessing data in; 2006-12-22 20:57:06 asta kernel [17181821.524000] sg_write: data in/out 12/12 bytes for SCSI command 0x43--guessing data in; 2006-12-22 20:57:06 asta kernel [17181821.528000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:57:06 asta kernel [17181821.528000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:57:06 asta kernel [17181821.528000] sg_write: data in/out 12/12 bytes for SCSI command 0x43--guessing data in; 2006-12-22 20:57:06 asta kernel [17181821.528000] sg_write: data in/out 12/12 bytes for SCSI command 0x43--guessing data in; 2006-12-22 20:57:06 asta kernel [17181821.532000] program kio_audiocd not setting count and/or reply_len properly 2006-12-22 20:57:06 asta kernel [17181821.532000] sg_write: data in/out 12/12 bytes for SCSI command 0x43--guessing data in; the same problem occured with opensuse 10.2. I can confirm this too. kscd will hang for several seconds/minutes until a ton of bus resets where done. The SCSI Bus resets also affect the performance of other SCSI devices like discs on the same bus. (scsi0:A:5:0): No or incomplete CDB sent to device. (scsi0:A:5:0): Protocol violation in Message-in phase. Attempting to abort. (scsi0:A:5:0): No or incomplete CDB sent to device. scsi0: Issued Channel A Bus Reset. 1 SCBs aborted sr1: CDROM not ready yet. last message repeated 5 times (scsi0:A:5:0): No or incomplete CDB sent to device. (scsi0:A:5:0): Protocol violation in Message-in phase. Attempting to abort. (scsi0:A:5:0): No or incomplete CDB sent to device. scsi0: Issued Channel A Bus Reset. 2 SCBs aborted sr1: CDROM not ready yet. .... many many more I've thought this problem is from cdparanoia as it also causes some problems because it uses very bad hacks for SCSI devices. So i've deinstalled cdparanoia completely to test what kscd would do. It was still hanging when i've tested it. So this is a serious problem affecting everyone using SCSI devices! Dear Bug Submitter, This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond. Thank you for helping us make KDE software even better for everyone! Dear Bug Submitter, This is a reminder that this bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? Thank you for helping us make KDE software even better for everyone! Hi Andrew, I'm afraid I cannot help with this bug anymore as I do no longer possess any optical SCSI drives. So if you wanna close this bug, feel free to do so. I suppose SCSI devices do not really play a significant role in modern computers anyway. kscd is no longer maintained, please switch to an alternative application. |
