Description Alan Matsuoka 2008-07-18 15:19:39 UTC
Description of problem:

When burning a DVD image, k3b claimed the written data
would differ. This is very irritating for users (adding more confusion
to the unreliable CD and DVD burning process).

The written data does not differ, but K3B seems to
write in 32KB blocks; when the ISO image is not
on a 32KB boundary it is filled up with NULLs.

Technicalls the Image is different, but K3B should
take this into account and not complain.

How reproducible:

Steps to Reproduce:
Write a dvd image, as one from -

$ ls -sk SUN_Ultra24_Supplemental_1.1_Bios_1.10_tools_and_drivers.iso
1168952 SUN_Ultra24_Supplemental_1.1_Bios_1.10_tools_and_drivers.iso

Actual results:
k3b complains that md5sum has failed

Expected results:
md5sum is correct, as shown in RHEL5.

Additional info:
probably upstream bug -

suspected fixes -

SEG Notes:

This appears to be a bug that occurs on x86_64 systems. I couldn't reproduce the
bug on x86 and since I haven't got a DVD burner on my x86_64 box I haven't got
any way of checking to see if the patch has introduced any regressions.

It doesn't seem to have any impact on my x86 system so I'll pass the patch up to
