thank you for your response. Trying to actualy run the driver with

You can cut the amount of log very much down by adding to
the beginning of dump_ptd() in isp116x.h the following
check:
if (PTD_GET_CC(ptd) == 0xf)
return;
I will try to set up some other debugging environment on Wendesday (I'm
out off office tomorrow) and than get back to you.
I thought a little bit more about it. It would be good to
print out some more info right before the BUG() is hit.
Could you please apply the patch below (I didn't test it,
hopefully it is clean).

PS! I am wondering whether the driver in newer kernels might
work better.

This log makes me ask that: what does HCRESET not comple\ ted yet! mean? How can I solve that? Maybe it's the original problem. I used the same .config file than for kernel 2.6.11.12, if you want I can send it too. No, don't send your .config. The HCRESET not completed yet message refers to a Host Controller reset. The driver sends a reset signal to the USB host controller and then waits 5 microseconds for the controller to finish resetting itself. If it hasn't finished, you get that warning. It's possible that your hardware needs more than 5 us. You can increase that delay time if you want, by editing the kernel source file drivers/usb/host/pci-quirks.c. Near the start of the file you'll see a routine named uhci_reset_hc which contains a line saying udelay(5); Try increasing the 5 to something like 50 or 100, to see if it makes any difference. From the fact that you still can't use your USB hard disk, it could be that the controller simply doesn't work at all. The only way to tell is by experimenting.

You can get to the usb_device from the usb_interface with a helper
function call, but if you want to save both pointers off too, that's
fine.

Not very useful and so far I did not found a way to reset rodents. No problems of that sort before I will try to suspend. Always something interesting.

I don't think anybody claimed this isn't a regression for the 600X.
I narrowed it further. The short story is that this commit (diff below
sig) makes the second S3 sleep go into the endless loop, if the loaded
modules are exactly thermal, processor, intel_agp, and agpgart:

If I boot with ec_intr=0, the second sleep works fine.
Here is the full story. First I tried a system with the minimal set of
modules to boot and run X (S3 sleep-wake wrecks the VGA consoles, but X
restores fine with 'chvt 1; sleep 0.5 ; chvt 7' on wakeup). So I
stopped every service and unloaded all modules possible, which left only
intel_agp and agpgart. Then, for each of the usual loaded modules
(except for sound modules, which often has sleep-wake problems anyway),
I tried:
1. Load the module
2. S3 sleep-wake-sleep-wake
3. Unload the module
to see whether the second sleep went into the infinite loop (visible
across the console). The one culprit I found was 'thermal' (which
brings in 'processor'). Other modules didn't trigger the problem.
Then I recompiled using a minimal config, with only networking (for X to
work) and the acpi modules, and maybe a few others that I couldn't
avoid, and retested to make sure 'thermal' still triggered the problem,
which it did. I used this config, or one just like it for 2.6.15, as a
base for all other kernels in the bisection search, using the nearest
ancestor's .config and then
yes '' | make oldconfig
to make the new .config
Eventually bisection converged to the commit above, and then I retested
that kernel with 'ec_intr=0'.
Is this a problem with the TP 600X hardware, in which case I'll just use
ec_intr=0 forever, or is there more software debugging (DSDT or related
to the diff)? I can turn on gobs of ACPI debugging and send the useful
parts of the log file.
In the bisection, many kernels worked fine, meaning that the second S3
cycle returned and I could compile the next bisection kernel. In doing
that I noticed another problem, that the fan would not turn on with some
of these good kernels even though the system was hot enough (plenty of
chance for it to turn on since the next compile heated up the CPU). For
example, acpi -t showed
Thermal 1: ok, 46.0 degrees C
Thermal 2: active[0], 42.0 degrees C
Thermal 3: ok, 31.0 degrees C
Thermal 4: ok, 34.0 degrees C
but the fan was off.
So whenever I had a good kernel (meaning taht S3 sleep-wake-sleep-wake
returned), I checked whether the fan would turn on, to collect data for
a separate bisection search. However, the data seems inconsistent. If
I feed the data to a fresh git bisect, it complains about one commit
being marked both good and bad. So I'll ask on the git list about that
issue.

Should anyone want to drink from the firehose that is 'redhat kernel bugzilla', let me know, and I'll see if I can't get a fedora-kernel-bugs mailing list or the like set up. Some subsystem maintainers (ACPI for example) really help out here, and add [EMAIL PROTECTED] to all the Fedora ACPI bugs. (I believe that list actually gets bug reports from other distro bugzillas too) (There's also a few 'meta-bugs' -- enter FCMETA_ACPI as a bug id and you get a link to a dependancy tree showing all the ACPI bugs reported. There's a bunch of those for various subsystems which makes it a little easier to track, though again, it's time-consuming just sorting through stuff). Off the top of my head, theres one for USB, SCSI, ACPI, ALSA, SATA (All with FCMETA_ prefix) Some of them are a bit sparse due to lack of time effort so far.

[linux-usb-devel] EHCI High speed periodic scheduler - ITD reuse problem
Hi, We are using TDI based High speed USB EHCI controller. Linux version is 2.6.12 I think that I found the problem with reuse ITD structures in the file ehci-sched.c The scenario that the problem happens is the following: We have High speed device with ISO endpoint, maxPktSize=1024 and Interval = 1 uframe Now Host test application (we using usbtest.ko with testusb.c) sending for example 10 URBs one after other. They will using 10 ITDs and will be put on periodic scheduler structure in the following way. Frame X: - itd7 - itd6 - itd5 - itd4 - itd3 - itd2 - itd1 - itd0 - NULL Frame X+1: - itd9 - itd8 - NULL So itd0 will be sent on uframe 0 of Frame X, itd1 on uframe 1 of Frame X, itd8 on uframe 0 of Frame X+1, itd9 on uframe 1 of Frame X+1, etc. Now assume itd0 was sent, so function itd_complete was called and itd0 will moved to stream-free_list, but itd1 still point to itd0 by hw_next field of struct ehci_itd Now exactly after that test application will send new URB. Function itd_submit() and itd_urb_transaction() will be called. Function itd_urb_transaction() first will try get ehci_itd structure from the free_list and will get itd0. Other functions will set all needed fields of ehci_itd structure and will link itd0 to Frame X+1 list. Frame X+1: - itd0 - itd9 - itd8 - NULL So itd0 should be sent on uframe 3 of Frame X+1. But HW still process uframe 2 of Frame X. When HW will process uframe 3 of Frame X the itd2 will be send first and in the same uframe itd 0 will be sent because itd0 still linked to itd1 in Frame X. On Frame X+1 itd0 will not be sent because it was sent on Frame X. It cause on miss-ordering of data sending and to bandwidth violations. I am not familiar enough with all corners of EHCI periodic scheduling, but it looks dangerous to unlink ehci_itd structure from Frame X list (change hw_next field) while the hardware still working on Frame X list. I see few possible solutions: 1. Don't move ehci_itd structure to stream-free_list during itd_complete function immediately, move all ehci_itd structures linked to Frame X list only when HW will start to process Frame X+1. 2. In the itd_complete function move ehci_itd structure to the tail of stream-free_list and in the itd_urb_transaction() function before reusing of ehci_itd structure from the stream-free_list check if HW already finished to process the frame that ehci_itd structure was linked before (itd-frame). I will be glad to hear about other possible solutions. Maybe somebody already meet the problem and there is patch for it.
