ECC errors

[Wojtek Puchar <wojtek@dracula.gda.osk.pl>]

I often get such things on my machine in first boot after power-up:

lca: machine check (la=0xfffffc0000208490,pc=0xfffffc000038d7b8)
  Reason: correctable ECC error (short frame, retryable, dc_stat=0):pn    
Correctable read error to memory occurred at address 3cb0cc0
    Several other correctable errors occurred.
 +       0 8000000000000040 ffffffff00000018 (*)
 +      10 0000000100000086 6fb0faf800000213
 +      20 0000000003cb0cc0 0000000000000000
 +      30 0000000200000002 0000007100000071


It's important that values in line with (*) are always the same,
and they comes no more when i shut down the system and reboot (without
turning off power).

What can it be - is my hardware defective, or is it software problem?

If someone have simple answer, please put it in first 80 chars
of mail message, so i will be able to read it as SMS with my GSM phone.

Thanks a lot for all help before (about caches etc.)
