Hi,

I've been running RT-0.7.26-3 already on both of my machines (P4/UP laptop
and P4/SMP-HT desktop) and I must say that overall stability seems to be
good.

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.
