I am having a very similar (possibly the same) problem. Started since I upgraded to 2.6.3-gentoo, I think. On 2.6.0-test* and 2.6.1 it worked fine. Kernel: 2.6.3-gentoo devfs (not udev) ide-scsi enabled, scsi cdrom support enabled, ide cdrom support disabled. (I am using an ide cd burner) /proc/scsi/scsi says Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: LITEON Model: DVD-ROM LTD163D Rev: GHR3 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: LITE-ON Model: DVDRW LDW-400D Rev: 1.2c Type: CD-ROM ANSI SCSI revision: 02 Reproducible: Always Steps to Reproduce: 1. k3bsetup or k3b 2. 3. Actual Results: Once the splash screen shows "Scanning for CD devices...", k3b enters uninterruptible kernel sleep and fills the logs with Feb 27 18:36:34 [kernel] ide-scsi: The scsi wants to send us more data than expected - discarding data - Last output repeated 22595 times - Expected Results: run normally (as in previous kernel versions) or at least show some kind of an error message
It seems this is a kernel 2.6.3 issue: http://lkml.org/lkml/2004/2/10/210
Yes if you are using ide burners but mine is an SCSI burner so should not suffer this problem?
Woot! Kernel 2.6.4-rc1 includes Jens Axboe's patch that fixes the problem! > Yes if you are using ide burners but mine is an SCSI burner so should not suffer this problem? If I understand the discussion on lkml and on k3b.org right, the issue affects all cd burners that go through the scsi interface on 2.6.3
Many thanks will try it out tomorrow.
fine, so we can close this one :)
