so why didn't you assign it to the kernel??? Unfortunately, I do not have a Pilot of any kind... Rob, can you switch to text mode (Ctrl-Alt-F1) before timeout and get me a picture with a webcam? There should be an oops (well, hopefuly. if not, we need to create one with sysrq or nmi_watchdog). See also bug 178873. Rob, I do need that oops very much. If nothing else, I'll see if it's the same problem as the 178873. I'll try and reproduce tomorrow (5/18) Created attachment 130980 [details]

traceback
if too hard to read, I can re-run
I need the precise kernel version, Rob. Then I use the binaries to match offsets and find the fault instruction. cat /proc/version is the best. Oh wait, silly me. The third traceback had the BUG statement with the line number, so I don't need to match offsets. Still, the version would be helpful. Also... Can you capture /proc/bus/usb/devices when the organizer is connected without crashing the box? That would be great. Created attachment 131025 [details]
Test fix 1
This is something to try. The patch attempts to prevent the scheduled work
to be run from a freed port memory.
kernel was 2122, though it's been broken in FC5 throughout. You have a built kernel? I can build one, but it'll take a bit of time. Rob, please try one at http://people.redhat.com/zaitcev/ftp/185409/ Also, if it crashes, I'd like the camera a little bit away from the screen. No longer crashes with the fix. OK, I think we fixed that at least upstream. 2.6.18-rc2 has the changes. Rob, I'll close it for now with "upstream", but please keep in mind that FC5 will only get the update after a rebase. Today's tip is 2.6.17-1.2157_FC5, which does not have the fix. |
