Part of my dmesg with any kernel later than Mar,17:

start_init: trying /sbin/init
ad2: invalid primary partition table: no magic
ad2: timeout waiting for READY
ad2: invalidating queued requests
 - resetting
ata1: resetting devices .. ata1: mask=03 ostat0=51 ostat2=00
ad2: ATAPI 00 00
ata1-slave: ATAPI 00 00
ata1: mask=03 stat0=50 stat1=00
ad2: ATA 01 a5

ad2: success setting PIO4 on generic chip

This can be somewhere explained, but "ad2: invalid primary partition table:
no magic" looks too strange :(

This is i815E MB with ICH2;
ad2: <IC35L040AVER07-0/ER4OA44A> ATA-5 disk at ata1-master
ad2: 39266MB (80418240 sectors), 79780 C, 16 H, 63 S, 512 B
ad2: 16 secs/int, 32 depth queue, tagged UDMA33
ad2: piomode=4 dmamode=2 udmamode=5 cblid=1
