I successfully burned a CD after installing this patch. (Only
55 MB of data, which might make a difference.) No kernel panic
or hangup, but I did get the following messages:
-----
Apr 16 12:14:35 venn kernel: scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 1, lun 0 VENDOR SPECIFIC(0xe6) 00 00 00 00 00 01 00 00 00
Apr 16 12:14:35 venn kernel: scsi0 : DANGER : command running, can not abort.

Do these messages indicate that there is still a problem?
