Elikkäs ongelma on tämä:
Minulla on koneessa 2 eri kiintolevyä, toinen on kokonaan ubuntun (9.04) käytössä, ja toinen alustettuna ext3. Kytkennät ovat IDE ja Sata.
Koneeni specsit ovat tässä:
MICRO-STAR INTERNATIONAL CO.,LTD
Intel Core 2 Duo E8400 @ 4.00GHz (Overclocked)
4072MB RAM
220 GB Total HD
NVIDIA GeForce 8800 GT
HD1: WDC WD1600AAJS-0 (150GB, sata)
HD2: SAMSUNG SP0802N (70gb, IDE)
Bootin aikana näyttöön tulee tämännäköinen viesti (Kernelin lokitiedostosta)

Tämä viesti toistuu kolme kertaa pienen viiveen jälkeen, jonka jälkeen vihdoin pääsen login-ruutuun. Molemmat levyt toimivat muuten virheettömästi.
Kun laitan biosista JMicron 363 ATA Controller asetuksen pois IDE modesta niin ongelmaa ei enää tule, ja boottaa nopeasti ilman virheitä, mutta eipä tunnista myöskään Samsungin läpyskää.
Koittelin tuossa jo googletella jonkin aikaa mutta enpä oikein vastausta saanut vaikka samanlaisia threadeja näytti löytyvän.
Tässä (ainakin omasta mielestä) tärkeä kokonaisuus kernelin lokista:

Tämähän ei siis mikään kauhea ongelma ole, kun kone on muutenkin lähes 24/7 pyörimässä mutta ärsyttävä silti. Kiitoksia jo näin etukäteen
