Sometimes hangs at "acpi bus type pnp registered"

Question

Sometimes, not always, my vaio vgn-c25g hangs at acpi bus type pnp registered when booting, ctl+alt+del does no t work, it's just freezed, I have to keep pressing the power button until the laptop shutdown and restart again.

Answer 1

100% sure. Here is the output of parted /dev/sdb print:
Model: ATA KINGSTON SV300S3 (scsi)
Disk /dev/sdb: 120GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 316MB 315MB ext4 boot legacy_boot
2 316MB 13.2GB 12.9GB ext4 var
3 13.2GB 21.8GB 8590MB linux-swap(v1) swap
4 21.8GB 120GB 98.2GB ext4 root
And the one for /dev/sda:
Model: ATA ST2000DM001-9YN1 (scsi)
Disk /dev/sda: 2000GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 32.3kB 2000GB 2000GB primary ext4
I am often booting on parted magic to check the drives. From this place I tried to copy a big amount of data using dd from /dev/null to a file on disk (100 Go). This was achieved without any problem. This is why I am so confused:
- on one side every symptom points to a damaged disk;
- but every test I tried indicate that the disk work like a charm.
