The patch titled x86: add workaround for bug in ASUS A7V600 BIOS (rev 1005) has been removed from the -mm tree. Its filename was x86-add-workaround-for-bug-in-asus-a7v600-bios-rev-1005.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: x86: add workaround for bug in ASUS A7V600 BIOS (rev 1005) From: Bertram Felgenhauer <int-e@xxxxxx> This BIOS claims the VIA 8237 south bridge to be compatible with VIA 586, which it is not. Without this patch, I get the following warning while booting, among others, | PCI: Using IRQ router VIA [1106/3227] at 0000:00:11.0 | ------------[ cut here ]------------ | WARNING: at arch/x86/pci/irq.c:265 pirq_via586_get+0x4a/0x60() | Modules linked in: | Pid: 1, comm: swapper Not tainted 2.6.26-rc4-00015-g1ec7d99 #1 | [<c0119fd4>] warn_on_slowpath+0x54/0x70 | [<c02246e0>] ? vt_console_print+0x210/0x2b0 | [<c02244d0>] ? vt_console_print+0x0/0x2b0 | [<c011a413>] ? __call_console_drivers+0x43/0x60 | [<c011a482>] ? _call_console_drivers+0x52/0x80 | [<c011aa89>] ? release_console_sem+0x1c9/0x200 | [<c0291d21>] ? raw_pci_read+0x41/0x70 | [<c0291e8f>] ? pci_read+0x2f/0x40 | [<c029151a>] pirq_via586_get+0x4a/0x60 | [<c02914d0>] ? pirq_via586_get+0x0/0x60 | [<c029178d>] pcibios_lookup_irq+0x15d/0x430 | [<c03b895a>] pcibios_irq_init+0x17a/0x3e0 | [<c03a66f0>] ? kernel_init+0x0/0x250 | [<c03a6763>] kernel_init+0x73/0x250 | [<c03b87e0>] ? pcibios_irq_init+0x0/0x3e0 | [<c0114d00>] ? schedule_tail+0x10/0x40 | [<c0102dee>] ? ret_from_fork+0x6/0x1c | [<c03a66f0>] ? kernel_init+0x0/0x250 | [<c03a66f0>] ? kernel_init+0x0/0x250 | [<c010324b>] kernel_thread_helper+0x7/0x1c | ======================= | ---[ end trace 4eaa2a86a8e2da22 ]--- and IRQ trouble later, | irq 10: nobody cared (try booting with the "irqpoll" option) Now that's an VIA 8237 chip, so pirq_via586_get shouldn't be called at all; adding this workaround to via_router_probe() fixes the problem for me. Amazingly I have a 2.6.23.8 kernel that somehow works fine ... I'll never understand why.
