Obecny subsystem pro SCSI naznal, ze nedokaze s tim zarizenim obnovit
komunikaci, tak ho odpojil. Vse nasledne (chyby pri zapisu, krece
reiserfs) uz jsou jen nasledky.

Zda se, ze ten FireWire nerozchodi nektere operace. Porovnaval jste tyhle
radky:

S jinymi pripady, kdy to ztuhlo? Mohla by tam byt nejaka zakonitost.
Format dulezitych casti by mel byt nasledujici:

       00 05 34 94 b7 00 00 f8 00
          `---------'    `---'
          adresa bloku   delka   (oboje v big endianu)

Mozna by take bylo na miste to otestovat na nizsi urovni, treba psat na
ten disk na ruzna mista pomoci dd.
