Subject2.6.11-rc4-mm1 and dpt_i2o Adaptec I2O RAID controller
Hi all,

i'm trying to get an Adaptec 2015S Zero Channel Raid Controller up and running in a very new Asus Mainboard (NCL-DS)
with Dual Xeons.
I already tried kernel 2.4.29 and plain 2.6.10 but both just lock up when loading the dpt_i2o driver.
With 2.6.11-rc4-mm1 i could gather the following output while booting:
Loading Adaptec I2O RAID: Version 2.4 Build 5go
Detecting Adaptec I2O RAID controllers...
ACPI: PCI interrupt 0000:09:01.0[A] -> GSI 11 (level, low) -> IRQ 11
Adaptec I2O RAID controller 0 irq=11
BAR0 f8880000 - size= 100000
BAR1 f8a00000 - size= 1000000
BUG: soft lockup detected on CPU#0!

I have several machines running with dpt_i2o raid controller and 2.4.29 for example but they are on older
Tyan boards.

Any suggestions how to get this controller up and running ? I suppose it has something to do with APIC and/or IRQ routing ?
If you need any additional information just let me know.

Best Regards,

Sebastian Faerber
