Description Ondrej Zary 2008-07-06 14:41:07 UTC
Hardware Environment: IT8212F-based controller in pass-through mode (pata_it821x.noraid=1) with Maxtor 7270AV hard drive connected

Problem Description: Kernel crashes on boot with the following text:

pata_it821x: forcing bypass mode.
pata_it821x: controller in pass through mode.
ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 11
ACPI: PCI Interrupt 0000:00:12.0[A] -> Link [LNKC] -> GSI 11 (level, low) -> 
IRQ 11
irq 11: nobody cared (try booting with the "irqpoll" option)

Comment 1 Tejun Heo 2008-08-29 07:16:09 UTC
Does "acpi=noirq" help?  If not, does "irqpoll" help?
Comment 2 Ondrej Zary 2008-09-03 12:00:25 UTC
It works fine with other hard drives. Should I try that options anyway?
Comment 3 Tejun Heo 2008-09-04 01:17:24 UTC
Hmm... in that case, acpi=noirq probably won't help much but irqpoll should.  Maybe the drive is raising IRQ spuriously.  Controllers with legacy TF interface just aren't equipped to cope with such situations.  I suppose this is always reproducible?  Does the drive work when paired with different controller?

Grabbing this one
Comment 5 Alan 2009-03-17 09:12:16 UTC
Please try 2.6.29 when it comes out
Comment 6 Ondrej Zary 2009-04-11 21:22:59 UTC
This bug is still present in 2.6.29.
