Hello!
I have made some tests with bonnie.

Kernel config was the same.
Write speed has fallen very much!!
And second problem: this computer (IBM PC server 315) wan't reboot
#reboot
syncing disks... done
(da1:ahc0:0:1:0) SYNCHRONIZE CACHE: CDB: 35 0 0 0 0 0 0 0 0 0

Rebooting...
or
#reboot
syncing disks... done
(da1:ahc0:0:1:0) SYNCHRONIZE CACHE: CDB: 35 0 0 0 0 0 0 0 0 0
(da1:ahc0:0:1:0) error code 9
Rebooting...
Error code change randomly (?)
And freeze...
System have
ADAPTEC 2940 ULTRA / ULTRA W BIOS v1.25
BROKEN_KEYBOARD_RESET i already tried
