Intel ICH8 errata for ata_piix.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have a laptop running Linux 2.6.33 with the following SATA chip:
"Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller (rev
03)", and I am experiencing random loss of data and a bouncing SATA
link.

The problem seems to be described by other people in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/297058 . After
investigating for a while, I found the errata
http://www.intel.com/Assets/PDF/specupdate/313057.pdf , see especially
errata #19 which handles MSI. Is this something that is handled in the
driver?

I have disabled MSI interrupts by using "pci=nomsi" on the kernel boot
line for now, and will see if it fixes anything - hopefully it does.
