Now after intensive use over the last 2 days, I realized that the internal harddisk works OK, but the dvd-drive did not after the 7th suspend/resume cycle - the device was suddenly gone (I could not even eject the disc I just inserted), more verbose dmesg follows: ata1: port is slow to respond, please be patient (Status 0x80) ata1: port failed to respond (30 secs, Status 0x80) ATA: abnormal status 0x80 on port 0x000101f7 ATA: abnormal status 0x80 on port 0x000101f7 ATA: abnormal status 0x80 on port 0x000101f7 ATA: abnormal status 0x80 on port 0x000101f7 ata1.00: qc timeout (cmd 0xa1) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1.00: revalidation failed (errno=-5) ata1: failed to recover some devices, retrying in 5 secs ata1: port is slow to respond, please be patient (Status 0x80) ata1: port failed to respond (30 secs, Status 0x80) ATA: abnormal status 0x80 on port 0x000101f7 ATA: abnormal status 0x80 on port 0x000101f7 ATA: abnormal status 0x80 on port 0x000101f7 ATA: abnormal status 0x80 on port 0x000101f7 ata1.00: qc timeout (cmd 0xa1) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1.00: revalidation failed (errno=-5) ata1.00: limiting speed to UDMA/33:PIO3 ata1: failed to recover some devices, retrying in 5 secs ata1: port is slow to respond, please be patient (Status 0x80) ata1: port failed to respond (30 secs, Status 0x80) ATA: abnormal status 0x80 on port 0x000101f7 sage repeated 4 times ata1.00: qc timeout (cmd 0xa1) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1.00: revalidation failed (errno=-5) ata1.00: disabled Soeren -- For the one fact about the future of which we can be certain is that it will be utterly fantastic. -- Arthur C.
