Public bug reported: Binary package hint: udftools
Bug in udftools or possibly in pktcdvd kernel module. Using Ubuntu Intrepid 32bit on an older PC with an ATHLON CPU and Samsung SH-S202J dvdwriter. with Linux version 2.6.27-11-generic (bui...@vernadsky) (gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu11) ) #1 SMP Wed Apr 1 20:57:48 UTC 2009 pktcdvd module filename: /lib/modules/2.6.27-11-generic/kernel/drivers/block/pktcdvd.ko license: GPL author: Jens Axboe <ax...@suse.de> description: Packet writing layer for CD/DVD drives srcversion: 4AF2F07A4806489F964C395 depends: cdrom vermagic: 2.6.27-11-generic SMP mod_unload modversions 586 and udftools 1.0.0b3-14 Following problems happen: 1) When booting with a CDROM or DVDROM in drive, Xorg starts with no keyboard and mouse, claiming that it was impossible to get them from hal 2) When 1 happens dvdwriters makes seek-like noise.

I do not know if 1) 2) 3) and 4) are different bugs and/or if they should be reported separately. 1) 2) and 3) appear strongly related. Indeed all points look serious. The possibility of data loss and the suspect that the drive might get damaged by the continuous seek is worring. I wonder if the data loss may be induced by writing with no or wrong power calibration. ** Affects: udftools (Ubuntu) Importance: Undecided Status: New -- udftools confuses hal https://bugs.launchpad.net/bugs/361041 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
