Hi List,

my kernel dies while probing parport with the following last words:

[    3.672199] parport_pc 00:0b: reported by Plug and Play ACPI
[    3.677969] parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,EPP,ECP,DMA]
[    3.687691] hwdev DMA mask = 0x0000000000ffffff, dev_addr = 0x0000000020000000
[    3.694916] Kernel panic - not syncing: swiotlb_alloc_coherent: allocated memory is out of range for device

I haven't started a bisection yet, but this seems to be introduced
somewhere between 2.6.26 and 2.6.27, at least 2.6.26 was working without
problems. The dmesg log + config was obtained from a kernel compiled
from git on 10/16/2008.

I've attached the configuration + dmesg log to this mail. Board is an ASUS
DSBF-D12 with 2 E5410 Processors.

Cheers,

Sven.
