Description Volker Hemmann 2009-01-04 23:01:55 UTC

Version:           all versions >0.12 (using Devel)
Compiler:          gcc 4.3.2 
OS:                Linux
Installed from:    Compiled sources

I have the same problem with ALL k3b versions greater than 0.12.17:
the drive is constantly polled. One second k3b 'sees' the empty media, the next one it is gone.
I can enable, disable hal flag. I can remove the drive from the hal polling or add it, no changes.
See also this bug:
http://bugs.gentoo.org/show_bug.cgi?id=235941
k3b is completly unusable. 

If I downgrade to 0.12.17 it 'magically' starts to work again. 
The drive is an ide nec burner in an external usb enclosure.

dmesg shows this:

I can confirm this problem on my laptop: OpenSUSE 11.1, k3b 1.0.5 on KDE 3.5.10, the dvd writer is an internal SATA drive:

kernel: scsi 0:0:0:0: CD-ROM            MATSHITA DVD-RAM UJ-832S  1.01 PQ: 0 ANSI: 5
kernel: sr1: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray
kernel: sr 0:0:0:0: Attached scsi CD-ROM sr1
kernel: sr 0:0:0:0: Attached scsi generic sg0 type 5

When k3b is running and an empty dvd is inserted, the system log shows lots of these messages:

kernel: ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
kernel: ata1.00: cmd a0/00:00:00:08:00/00:00:00:00:00/a0 tag 0 pio 16392 in

kernel:          res 40/00:03:00:0c:00/00:00:00:00:00/a0 Emask 0x4 (timeout)
kernel: ata1.00: status: { DRDY }

kernel: ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
kernel: ata1.00: configured for UDMA/25
kernel: ata1: EH complete

During this, k3b keeps recognizing the empty medium, and then loses it again.

In contrast, when k3b is NOT running, inserting the empty disc shows the following once:

kernel: end_request: I/O error, dev sr0, sector 0
kernel: Buffer I/O error on device sr0, logical block 0
kernel: end_request: I/O error, dev sr0, sector 0
kernel: Buffer I/O error on device sr0, logical block 0
kernel: cdrom: This disc doesn't have any tracks I recognize!

Burning with braserio or other tools then works without any problems, so this seems indeed to be a problem with k3b.

Hi,

I installed kde svn on tuesday and k3b svn today and good news:
it just worked. No constant polling, nothing. Just clean burning.

Hal version is 0.5.12_rc1-r4

so I can mark this as fixed now. :)

Comment 4 Volker Hemmann 2009-05-28 11:04:05 UTC

I still have to try kde 3.5.XY but I am not very enthusiastic about it ;)
