Per you are right, but if I configure the policy in that way, that hal shouldn't poll cd/dvdrom, and he (she, it) blocks the bus anyway, it's not acceptable, and if this behaviour was also in previous releases (it wasn't) it would be ok, not really, but I 've to live with that. I know there are different hal versions for 2.6.x kernels, one for less than 2.6.13 and one for above, maybe there is the problem.
Further steps: Due the fact that this bug is unconfirmed, I will try on my spare harddisk an "old-school" gentoo installation (I'm more familar with gentoo than with debian-unstable), with nearly same kernel, udev,dbus,hal version, and will check if there is the same problem, an if no, I will check what the friendly gentoo guys did (which patches they apply) regards -- hald blocks ide bus if cdrom on same bus with harddisk(was:Extremly slow IO performance with dapper, high wa% on Dell Inspiron 8200) https://launchpad.net/bugs/48499 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
