dla przypomnienia, moja plyta to ABIT BE6 II i HPT370, dysk Seagate Baracuda4 
40GB...

to jest fragment dmesg z kernela 2.2.21-4, start systemu:
------------------------------------------------------------------------------------------
HPT370: IDE controller on PCI bus 00 dev 98

---------------------------------------------------------------------------------------------------

po czym wykonuje sie hdparm z opcjami -c1 -d1 ....
gdy juz system sie odpalil, wklepuje hdparm /dev/hde i otrzymuje:
/dev/hde:
 multcount    = 0 (off)
 IO_support   =  1 (32-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 BLKROGET failed: Input/output error   <----------- ????
 readahead    =  8 (on)
 geometry     = 77545/16/63, sectors = 78165360, start = 0

przy kernelu 2.2.20-18, dmesg wygladal standardowo, wszystkie dyski wykrywaly 
sie normalnie no i po wydaniu polecenia hdparm /dev/hde, otrzymuje:
/dev/hde:
 multcount    =  0 (off)
 IO_support   =  1 (32-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 77545/16/63, sectors = 78165360, start = 0

gdy zapodam - hdparm -i /dev/hde:
/dev/hde:

ta sama operacje wykonam na 2.2.21-4, jak tylko zresetuje serwer, narazie 
wrocilem do 2.2.20-18 ....

dodam jeszcze ze na innym sprzecie mam czipset i845, dysk taki sam, tyle ze 
60GB i wszystko jest OK

z gory THX za pomoc
