However I still have some pending complaints ;) These are the ones that are troubling my confidence: 1) Almost everytime the P4/SMP box locks up while unloading the ALSA modules e.g.on shutdown. This has been an issue for quite some time on the latest RT patches, not exclusive to RT-V0.7.26-3. Probably it started since the merge into -mm3, but not sure. One thing to note is that, when the nmi_watchdog=1 boot parameter is set, this lockup behavior seem to be avoided. This isn't quite an issue on my other P4/UP (laptop), but it segfaults sometimes too, while rmmod'ing the alsa modules. It doesn't lockup thought, and the corresponding tracedump can be pasted from syslog (see attachment). Unfortunately this is the only cross-evidence I could gather, and hope it helps to a clue, just because... 2) Serial console (or netconsole, if that matters) aren't showing anything relevant for debugging; SysRq-T is just silent, only printing a "Show State" one liner. No traces, no dumps. 3) USB hotplugging is not working as it should be on my P4/UP laptop (ohci_hcd), althought it seems to work on the P4/SMP-HT desktop (uhci_hcd). USB devices are only recognized if and only if already plugged at boot/init time; plugging in on a later time doesn't get listed by 'lsusb', but a single 'wakeup' message shows _once_, and only once, on syslog/dmesg. Unplugging and/or plugging in back again, gives you nothing not even that 'wakeup' message. As reported a few days before, this really seem to be introduced by -mm3 (and still an issue on -mm4, FWIW). I'm just asking for hints here, as one of the main uses of the RT kernel on my laptop is about using a Tascam US-224 USB Audio/MIDI controller interface, which is USB 1.1 based and have been quite successful with it, at least until (and including) -mm2-RT-V0.7.11 . OK. Just some last resort questions: is there any plans (or recipe) on merging the RT patch(es) against the 2.6.10(-rc1) vanilla kernel? Or, at least for my laptop's sake, on top of this late and "well" behaved -mm2 ? Hope someone knows it better ;) Cheers. -- rncbc aka Rui Nuno Capela rncbc@rncbc.org ------=_20041115143347_85895 Content-Type: text/plain; name="messages.0-2.6.10-rc1-mm3-RT-V0.7.24"
