OK, I don't want to rule out a software problem. However, I would advise to use Taiyo Yuden media if you still can those. Those are usually those with the highest quality and reliability. > I am getting a lot of other messages for unaligned transfers on /dev/sr0, too: > > Oct 11 20:11:49 kernel: [ 28.658188] sr 0:0:4:0: [sr0] scsi-1 drive > Oct 11 20:11:49 kernel: [ 28.659165] cdrom: Uniform CD-ROM driver Revision: > 3.--More-- (32% of 53020 > Oct 11 20:11:49 kernel: [ 28.706039] sr 0:0:4:0: Attached scsi CD-ROM sr0 > ... > Oct 11 20:11:49 kernel: [ 30.755843] sr 0:0:4:0: [sr0] tag#20 unaligned > transfer > Oct 11 20:11:49 kernel: [ 30.756820] blk_update_request: I/O error, dev > sr0, sector 583127 op 0x0:(READ) flags 0x0 phys_seg 9 prio class 0 > Oct 11 20:11:49 kernel: [ 30.759749] Buffer I/O error on dev sr0, logical > block 583127, async page read > Oct 11 20:11:49 kernel: [ 30.760726] Buffer I/O error on dev sr0, logical > block 583128, async page read > ... etc.. > > Getting the full log would be a bit tedious, as I can't proceed to the network > configuration... I had another idea after I replied your last mail and I think one possible culprit could be xorrisofs which was used for building the ISO image instead of genisoimage which Debian used in the past. I can actually create an installation image with genisoimage instead and you can test it. Also, let's pull Thomas Schmitt from libburnia upstream who might know more. >> FWIW, the change to re-enable EISA on alpha in the Debian kernel config has >> not been >> merged yet due to bike-shedding over the proper changelog entry ...
