Lukas Hejtmanek, I have to say, that I've heard this subject before, the summary answer seems to be, that the kernel can not guess the wishes of the user 100% of the time. If you have a low priority I/O task use ionice(1) to set the priority of that task so it doesn't nuke your high priority

linux-2.6.10 has some bio problems that are fixed in the current linux-2.6.11 release candidates. The bio problems wreaked havoc with XFS and there were people reporting EXT3 problems as well with this bug. I'd recommend trying the latest release candidate and see if your problem vanishes.
