It looks like a general sata issue. Here a link to the thread: > > http://forums.gentoo.org/viewtopic-t-482731.html I'd suggest that you generate a kernel profile while the sluggishness is happening. Boot with "profile=1" on the kernel boot command line. Then run: readprofile -r do-sluggish-thing readprofile -n -v -m /boot/System.map | sort -n -k 3 | tail -40 Or, better-but-more-complex: oprofile. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
