SATA ports, various libata error messages

English Hardware
1

Hi there,

I am running into some problems with SATA ports, harddisks, libata, etc.

Setup:

  • Asus M3N-H board, Geforce 8300 chipset
  • opensuse 11, kernel 2.6.25.20
  • various harddisks (old and brandnew) on various SATA ports give various error messages in /var/log/messages - see below. I doubt these are hardware problems (even the old disk works without problems in a windows box)
  • Bios set to AHCI

The libata page isnt too helpful it finding problems. Tried kernel options ahci=off (X11 does not start), pci=nomsi (no improvement), noapci (no improvement). irqpoll as boot kernel option seems to help (?), but is unacceptably slow.

googling just brings up many messages like mine :-\

Any help really appreciated!

Thanks

Holger

Try noapic kernel parameter, it works for me. I submitted this as a bug long time ago, unfortunately the developers had no idea how to fix it… :frowning:

Hi there,

thanks for the pointer. noapic did not help with the 2.6.25 kernel (for whatever reason), but a kubutuntu 9.04 beta with the 2.6.28 kernel and noapic does reduce the SATA link resets considerably. Now, there is about one such reset every five to ten minutes.

Still not nice, but sort of bearable…

thanks & best,

Holger
