I am trying to upgrade an old PC from Slackware 12.1 (udev-118, Linux-2.6.24.5) to Slackware 12.2 (udev-135, Linux-2.6.27.7). The system hangs up during boot running cdrom_id. If I disable 60-cdrom_id.rules, or replace cdrom_id with the one from udev-118, it works. Running cdrom_id from udev-135 (138 too) logs lots of messages like those shown below, and never completes. The drive is an IDE Sony CD-RW CRX175E2, connected to an Intel SE440BX2 motherboard, and the drive works fine other than this issue. How do I troubleshoot this? kernel: hdc: status error: status=0x59 { DriveReady SeekComplete DataRequest Error } kernel: hdc: status error: error=0x20 { LastFailedSense=0x02 } kernel: ide: failed opcode was: unknown kernel: hdc: drive not ready for command ... -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
