Recently (1-2 months) I bought a new laptop from system76 (model - Gazelle,
16G memory, 500G disk) and suspect there may be h/w issues. Any
suggestions/pointers are welcome.

1. Memory errors

While booting it reports these messages

[    0.000000] *BAD*gran_size: 64K     chunk_size: 16M     num_reg: 10
lose cover RAM: -8M

Ran memtest and it started reporting lot of errors - but there is a
reported defect on memtest for ubuntu 12.10 -  memtest86+ test #7 false
positives (random number sequence error) -
https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/1071209
How to determine if there is a memory stick issue? I dont have any
spare/equivalent memory.

2. Hard disk
Further down, it shows some info about disk

[    3.472751] EXT4-fs (sda1): INFO: recovery required on readonly
filesystem
[    3.472753] EXT4-fs (sda1): write access will be enabled during recovery
[   11.728764] EXT4-fs (sda1): recovery complete
[   11.755158] EXT4-fs (sda1): mounted filesystem with ordered data mode.
Opts: (null)
[   13.835099] Adding 16666620k swap on /dev/sda5.  Priority:-1 extents:1
across:16666620k

Ran the disk utility and smart data report shows lot of out of range values
- airflow temperature 46 C/115 F (failed once in the past)
but overall health assessment is listed as  'OK'.
There appears to be some unaccounted space as well - does the system
reserve some space by default which is not reported at all?
used space -  20G - (from gparted)
swap           -  15G
unused        - 430G
Total            - 500G - what about the remaining 35G?

Thank you,
Vasu
