Comment 1 Pete Zaitcev 2006-08-22 17:46:03 UTC
I beleive in honesty as the best policy, so I regret to say that I'm going to
ignore this report for now. The reason is, the PCI target abort is always
horribly difficult to diagnose, and 95 out of 100 it's caused by BIOS
reprogramming something behind our back.

That said, we ought to have uhci-hcd restarting its UHCI after a halt.
I'll look into that, but not into root-casing this bug.

Comment 2 Pete Zaitcev 2006-08-22 17:47:09 UTC
Oh, BTW. If you boot an old kernel from FC5, does that work?

Comment 3 Richard Allen 2006-08-22 18:08:03 UTC
Yes, I've been running FC5 on this machine without fail.  Did you want me to
install an FC5 kernel on the fc6t2 system and try again ?

Comment 4 Pete Zaitcev 2006-08-22 18:21:46 UTC
Yes, I would with but I am not sure if it's possible, because of udev
dependencies. If we could somehow narrow it down to a couple of kernel
releases, that would be great...

Comment 5 Richard Allen 2006-08-22 18:27:05 UTC
Ok. I'll do my best.   But we do know that the latest errata kernel for FC5
(2.6.17-1.2174_FC5smp) works like a charm (on FC5 that is) so the problems
begins after that.
Due to the time it can take to reproduce this (unfortunatly it does not happen
right away) my testing will take some time.

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.


I am CC'ing myself to this bug, however this version of Fedora is no longer

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!
