Yet another "me too" here. Exact same symptoms as the OP - the system freezes just after a burn has finished. The mouse and console are dead and I can't ssh in from another box ("no route to host"), but I _can_ use Alt-SysRq-[U,S,B] to restart the computer, so it's not as though the system has hard locked.
This has happened multiple times, and each time it happens, the burned disk is usable afterward - I have yet to end up with a coaster. There is nothing in /var/crash., but the system did manage to tack these few lines onto the end of /var/log/messages before I forced the restart: ========== Aug 20 22:35:54 swan kernel: [187390.252345] hdc: irq timeout: status=0xd0 { Busy } Aug 20 22:35:58 swan kernel: [187390.252351] ide: failed opcode was: unknown Aug 20 22:36:09 swan kernel: [187398.621151] hdc: irq timeout: status=0xd0 { Busy } Aug 20 22:36:09 swan kernel: [187398.621158] ide: failed opcode was: unknown Aug 20 22:36:22 swan kernel: [187407.597348] hdc: irq timeout: status=0xd0 { Busy } Aug 20 22:36:22 swan kernel: [187407.597356] ide: failed opcode was: unknown Aug 20 22:36:59 swan kernel: [187427.085845] cdrom: This disc doesn't have any tracks I recognize! ========== The next lines after these are boot messages from the restart that followed the freeze. This happens with DVD's, but I have not tried burning a CD recently (don't have any blanks handy) We use K3B to burn with. Per gudwin's suggestion, un-checking the "don't eject when finished" option in the "Advanced" section of the config dialog seems to have worked for me. K3B now properly finishes the burn and ejects the disc without any hangs (except that HAL gets in the way and K3B has to try a couple of times to successfully eject). Just did four completely unique burns in a row without a problem. The machine is custom-built: Gigabyte K8U-939 mainboard with an AMD 64x2 3800+ CPU, 1 GB RAM, 80 GB no-name SATA hard disk, IDE Lite-On SHW- 160P6S burner, nVidia MX4000 video. Using the regular 32 bit version of Hardy, kernel is "2.6.24-19-generic". For whatever it is worth, this system also suffers from that same annoying problem of not being able to open/eject an empty drive via the front panel button. Gentoo also experienced both the freeze issue we're talking about here, and the empty-drive-eject issue, so this definitely goes upstream to...well, somewhere! :-) -- K3B is freezing system AFTER burning DVD https://bugs.launchpad.net/bugs/119258 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
