Anyone know what it means? The process accessing the CD hangs for about 15 seconds or so, then the system freezes for 1-2 seconds and then everything works like a charm. scsi : aborting command due to timeout : pid 28, scsi1, channel 0, id 0, lun 0 Read Capacity 00 00 00 00 00 00 00 00 00 hdc: irq timeout: status=0xd0 { Busy } hdc: DMA disabled hdc: ATAPI reset complete hdc: irq timeout: status=0xd0 { Busy } hdc: ATAPI reset complete hdc: status error: status=0x51 { DriveReady SeekComplete Error } hdc: status error: error=0x60 scsi1 channel 0 : resetting for second half of retries. SCSI bus is being reset for host 1 channel 0. ide-scsi: Strange, packet command initiated yet DRQ isn't asserted ISO 9660 Extensions: Microsoft Joliet Level 1 ISOFS: changing to secondary root The drive is an LG GCC-4120B DVD/CD-RW drive attached to a VIA vt8235 controller, 2nd channel, single drive. Using ide-scsi emulation. The problem is harmless though. At least it hasn't caused any further problems.
