It seems it boots successfully sometimes, but that (I think) depends on the order the devices are enumerated. I grabbed a dmesg of both a fail and success, and spotted a couple of differences (if it helps)--note I don't see any line about HPA, yet the old ide driver detects it (Host Protected Area detected, followed by disabled) so I apparently do have it... (- is fail, + is successful boot):
-ata1.00: 78125000 sectors, multi 16: LBA +ata1.00: 80043264 sectors, multi 16: LBA -SCSI device sda: 78125000 512-byte hdwr sectors (40000 MB) +SCSI device sda: 80043264 512-byte hdwr sectors (40982 MB) -SCSI device sda: 78125000 512-byte hdwr sectors (40000 MB) +SCSI device sda: 80043264 512-byte hdwr sectors (40982 MB) - sda: p3 exceeds device capacity -attempt to access beyond end of device -sda: rw=0, want=80043080, limit=78125000 -Buffer I/O error on device sda3, logical block 9864768 Besides the obvious disk size discrepancy, the only other noticable difference is that my network card gets initialized BEFORE the ATA driver in the successful bootand AFTER the ATA driver in the failed boot... so maybe it's an ACPI issue? HTH, I see Kyle mentioned testers a couple of weeks ago, I'm not sure if that's what was in mind :). -- pata driver in libata not mounting /home https://launchpad.net/bugs/82314 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
