I had this message frequently in 10.3/x6_64 and local opinion was a failing disk. Changed disk, build 11.0b3 and it reappeared so changed IDE cable and it stopped -- for two days and then came back after a reboot for the new kernel, about every 4 mins or so.

It seemes like a controller problem to me, rather than a disk problem. Why is is using PIO? Do you have the proper 80 pin cables?

I would open a bugzilla and try to assign it to Heo Tejun. He is Novell's sata driver expert.

you can solve this problem (that made me definitively abandon Fedora for Suse) simply replacing your ata controller with its non-libata counterpart: e.g. I had to remove sata_via in favor of vt82cxxx. According to my readings this bug exhibits itself with controllers that have both sata and pata ports. It's been in the kernel for many months (maybe years) and I'm extremely surprised that it was never fixed (as far as I can tell). Fortunately Suse didn't make the idiot choice to remove non-libata based drivers that Fedora did. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That is no solution, drivers needs fixing/workaround instead.

Historically the Linux 2.6 kernel has had some situations where they only supported the PATA connections of a controller or the SATA connections. I believe dual support has been to most by now, so I don't know if any drivers are still hobbled like that in 2.6.25 or not. Thus if a user had one of those, they either had to choose one half of their controller to use, or get a different controller. I believe one workaround was to run the controller in "legacy" mode and use the PATA driver.

They may be removed at some in the future though, but that's something kernel people decides.

The old drivers/ide subsystem is likely to be in vanilla kernels for a year or two longer (or more), but it can be disabled during kernel compile. I gather from Nico's comment that Fedora has quit building them into their kernels. A surprising situation, but certainly technically feasible.
