Hello Tejun,
I want let you know, that the following laptop would need to be included
in the list of the 32bit DMA boards.
First I have used the snapshot 2.6.31-git and was not able to boot until
I reversed the patch 58a09b38cfcd700b796ea07ae3d2e0efbb28b561.
I have tried it with the snapshot 2.6.31-git2 and was not able to boot.
I have checked the latest bios (1.10c) for this laptop and it did not
worked.
I will attache the dmidecoder output (don't know if this helps).
Can you please verify the attached patch fixes the problem? This should
apply cleanly to 2.6.31.
Thanks.
I have tried the attached patch on a clean 2.6.31 source and it is working.
dmesg is showing the following:
libata version 3.00 loaded.
ahci 0000:00:12.0: version 3.0
ahci 0000:00:12.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
ahci 0000:00:12.0: ASUS M2A-VM: BIOS too old, forcing 32bit DMA, update BIOS
ahci 0000:00:12.0: controller can't do 64bit DMA, forcing 32bit
ahci 0000:00:12.0: AHCI 0001.0100 32 slots 4 ports 3 Gbps 0xf impl SATA mode
ahci 0000:00:12.0: flags: ncq sntf ilck pm led clo pmp pio slum part
Will try it later on the latest git, I think the dmesg should identify
the Board correct then and.
Thanks,
Holger
