If this is the case, a grub-reboot is issued to boot into windows XP once, otherwise the image is restored onto the HDD. If I reboot from windows XP, the linux OS should do the above again. On an actual machine, the procedure works without a hitch. However after a reboot from windows XP to linux (Start | Shut Down... | Restart) the linux suddenly can't find the SATA disks. dmesg has the following lines: {{{ [ 6.166426] ata1.00: qc timeout (cmd 0xec) [ 6.166426] ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 6.516437] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 16.517619] ata1.00: qc timeout (cmd 0xec) [ 16.517619] ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 16.517619] ata1: limiting SATA link speed to 1.5 Gbps [ 16.866406] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 46.866424] ata1.00: qc timeout (cmd 0xec) [ 46.866424] ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 47.216399] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 47.566424] ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 52.566425] ata2.00: qc timeout (cmd 0xec) [ 52.566425] ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 52.916425] ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 62.916398] ata2.00: qc timeout (cmd 0xec) [ 62.916398] ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 62.916398] ata2: limiting SATA link speed to 1.5 Gbps [ 63.266424] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 93.266437] ata2.00: qc timeout (cmd 0xec) [ 93.266437] ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 93.616439] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 310) }}} Attached is the full vbox.log and the full dmesg as I have it.",defect,reopened,other,VirtualBox 3.2.10,,,,Linux,Windows
