Tuhnutie servera

[Ján Koštial]

Zdravím všetkých.
Prosím o radu, tuhne mi server.

Genéza: 
Existoval funkčný server v zostave:    
    AMD DURON 700, 128MB RAM, MB ASUS KT7RAID,
    2x 30GB HDD MAXTOR IDE, 7200ot./min.
    Linux RedHat6.1
Nedávno prešiel upgrejdom:
    vymenené disky za SCSI IBM DDYS-T18350N Ultra160
    s radičom Adaptec AHA-19160
    Nová inštalácia Linux RedHat7.2, kernel 2.4.7-10

Od tej doby tuhne - usudzujem, že príčinou bude to SCSI.
Server niekedy zatuhne natvrdo - bez hlášky - pomôže len HW reset.
Niekedy zatuhne len niektorý proces - napríklad je možné sa prihlásiť z inej konzoly.
Niekedy server vypíše niečo takéto:
Oops: 0000
CPU:    0
EIP:    0010:[<c8807a53>]
EFLAGS:    00010297

            ...
Code: 8b 7c 15 04 ...
 <0>Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing
    
Nepomohlo ani prepnutie radiča zo 160MB/s na 80MB/s - ale to by som tam aj tak nechcel natrvalo.
Disky majú nastavené ID 3 a 4, Terminátor je na kábli.
Poraďte, čo s tým.
    Iný driver? 
    Ako má byť správne nastavený radič? 
    Ako majú byť správne nastavené prepojky na diskoch?
    Vadí zdieľanie IRQ na PCI?

Vďaka za akúkoľvek radu.

Lucky.
