Здравствуйте, уважаемые господа.

Имею железку ASUS pundit h1-ph1.

привожу top:

last pid:   861;  load averages:  0.26,  0.15,  0.09                                          up 0+00:45:22  12:00:35
37 processes:  1 running, 36 sleeping
CPU states:  0.5% user,  0.0% nice,  0.5% system, 89.3% interrupt,  9.8% idle
Mem: 18M Active, 9268K Inact, 17M Wired, 16M Buf, 166M Free
Swap: 421M Total, 421M Free

мучает загрузка проца по interrupt - 90% (!).
как побороть?  

при установке с загрузочного диска ядро запустилось без только без acpi.

привожу dmesg.boot:

irq11: atapci0  очень много прерываний.

Очень может быть. Что-то мне помниться, были проблемы драйвера ядра
с пишущими CD.  
Попробуйте пока отключить CD , master'ом сделать диск .
Не забудьте по /etc/fstab .

atapci0: <ATI IXP400 SATA150 controller> port 0xff00-0xff07,0xfe00-0xfe03,0xfd00-0xfd07,0xfc00-0xfc03,0xfb00-0xfb0f mem 0xfe02f000-0xfe02f1ff irq 11 at device 18.0 on pci0
ata2: <ATA channel 0> on atapci0
ata3: <ATA channel 1> on atapci0

Но искать надо здесь .

^^^^^^^^^^^^^^^^^^^^^^
Вот оно 11  прерывание на  atapci0 .

Надо временно попробовать в BIOS или на плате запретить
ata2: <ATA channel 0> on atapci0
ata3: <ATA channel 1> on atapci0

SATA контроллер наверно "гадит".

Диск и CD у Вас здесь :
atapci1: <ATI IXP400 UDMA133 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xf900-0xf90f at device 20.1 on pci0
ata0: <ATA channel 0> on atapci1
ata1: <ATA channel 1> on atapci1

Отключил CD, поставил мастером HDD, ситуация не изменилась.

В итоге проблема решилась переводом из SATA в IDE, в биосе.
