[Bug 746958] [NEW] brasero burn operation fails with "Power calibration area error"

Binary package hint: brasero

On a Maverick amd64 system with brasero 2.32.0-0ubuntu2.2, I have
recently experienced the following error while burning single-layer
DVD+R's:

Error while burning.
SCSI error on write(256,16): [3 73 03] Power calibration area error

This has happened twice in a row while attempting to burn the Natty Beta
1 i386 live DVD (ubuntu-11.04-beta1-dvd-i386.iso, md5sum
8057e46487448c7bf5a1c39ec4408c5a). But before that, Brasero *did*
succeed at burning this. All three times (the successful burn and the
two failed burns) were on this same system. No packages were upgraded
between the burns. Brasero was exited between each run and the
subsequent run. All three times, writeable DVD media from the same spool
were used. All three times, I had selected a burn speed of 2.4x (even
though that is lower than the maximum that Brasero indicates is
supported by my drive), though the first time (when the burn succeeded),
it seemed to be indicating that this speed was being exceeded some of
the time. I have attached the log file produced by the third attempt
(i.e. the second unsuccessful attempt). That is the attempt whose
running instance of Brasero's PID I invoked ubuntu-bug with, to report
this bug. I will also attach the similar log file from the previous
failed attempt.

In case it's relevant, the .iso file I was burning (and then attempting
unsuccessfully to burn again) was located on an NTFS partition (of the
same physical disk on which the Ubuntu system is installed). It was
accessed through a symbolic link. Specifically, the full path of the
file being burned was
/home/ek/Torrents/Complete/ubuntu-11.04-beta1-dvd-i386.iso; /home/ek is
located on /dev/sda7, but /home/ek/Torrents is a symbolic link to
/media/Wingardium/Users/ek/Torrents, which is a directory on /dev/sda3.

This is on a Sony Vaio VGN-NW310F laptop. I don't have a particularly
good source of technical details on my optical drive, but the technical
information at
http://www.newegg.com/Product/Product.aspx?Item=N82E16834117986 may be
somewhat useful.

The output of "uname -a" is:

Linux Apok 2.6.35-28-generic #50-Ubuntu SMP Fri Mar 18 18:42:20 UTC 2011
x86_64 GNU/Linux

I'll attach the output of "lspci", "sudo lshw", and "lsmod".

This is probably the same bug as bug 700975. The error message is the
same. But that bug doesn't provide a lot of information, so perhaps this
is not the same bug...and even if it is, I figured it might be useful
for me to file a separate report, with more information. Furthermore,
that bug report suggests (though not conclusively) that bug 700975
occurred specifically when burning an image across a Samba share, which
does not pertain here.
