Hi everyone,

My Vaio Z1390, installed with Adam's modified kernel (2.6.37), is having 
intermittent SSD disk errors. I am trying to figure out if this is a 
kernel or power management issue or a disk problem. My installation is 
on the raid disk /dev/mapper/isw_cdjgeihaei_Volume05, but the real 
drives show up as /dev/sda and /dev/sdb.

Does anyone have these intermittent disk errors?
When I do a smartctl test on the drives, they are OK:

smartctl -t long /dev/sda
smartctl -t long /dev/sdb
(wait 12 minutes)
smartctl -l selftest /dev/sda
smartctl -l selftest /dev/sdb

both shows that there is no error in selftest.

However, the smart registers keep in memory the last disk error that 
happened.
    smartctl -a /dev/sda
shows information like:

Error 383 occurred at disk power-on lifetime: 196 hours (8 days + 4 hours)
  When the command that caused the error occurred, the device was 
active or idle.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH
  -- -- -- -- -- -- --
  84 51 40 00 53 4d e8  Error: ICRC, ABRT 64 sectors at LBA = 
0x084d5300 = 139285248

  Commands leading to the command that caused the error were:
  CR FR SC SN CL CH DH DC   Powered_Up_Time  Command/Feature_Name
  -- -- -- -- -- -- -- --  ----------------  --------------------

mode]
  27 00 00 00 00 00 e0 00      05:25:06.086  READ NATIVE MAX ADDRESS EXT

and "smartctl -a /dev/sdb" shows

Error 321 occurred at disk power-on lifetime: 228 hours (9 days + 12 hours)
  When the command that caused the error occurred, the device was 
active or idle.

Does this mean something to someone? :-)
I welcome any suggestions.
Cheers,
