PROBLEM: EHCI Driver hard-locks system when USB devices plugged.(2.4.21 & 2.6.0-test2)
From: Alexander Markley
Date: Sun Aug 10 2003 - 20:54:40 EST
I'm sure you guys in this list just thrill with delight when a bug
report comes in. Keeping that in mind, I have attempted to make this the
most complete bug-report possible. I am using the template for bug
reports that is in the root of the source tree. (If there is too much
here, sorry... Just following the bug report template.)
NOTE: Please CC messages about this to me, since I can't stay on the
mailing list for long.
This problem has occurred with all of the recent kernels that I have
tested. This includes 2.4.X and 2.6.0-testX.
Please note that most of the diagnostics preformed as per the template's
recommendations were preformed while running 2.4.21.
The kernel boot messages were copied by hand from 2.6.0-test2, with USB
verbose debugging and kernel debugging turned on. (Copied by hand
because you can't cut/paste on a crashed kernel.) (Don't make me swear
by every jot and tiddle in those messages, since I copied 'em by hand. I
am confident, however, that the important stuff is right.)

BEGIN FILLED-OUT TEMPLATE
[1.] One line summary of the problem:
PROBLEM: EHCI Driver hard-locks system when USB devices plugged.
(>=2.4.X)
[2.] Full description of the problem/report:
This problem applies to all 2.4 kernels that I've tried, and
2.6.0-test2. When I have EHCI built in, and I have USB devices plugged
in, the kernel never gets past initializing EHCI. If I boot without USB
devices, and plug them in after the booting process, the system
hard-locks wherever it was. (No console, no network, no disk activity,
nothing.)
[3.] Keywords:
USB, EHCI, 2.4, 2.6, kernel, bug, crash
[4.] Kernel version (from /proc/version):
2.4:
[root@elbmin3 usb]# cat /proc/version
Linux version 2.4.21 (root@elbmin3) (gcc version 3.2.2 20030222 (Red Hat
Linux 3.2.2-5)) #2 SMP Wed Jul 30 16:56:41 EDT 2003
[root@elbmin3 usb]#
2.6:
[root@elbmin3 root]$ cat /proc/version
Linux version 2.6.0-test2 (root@elbmin3) (gcc version 3.2.2 20030222
(Red Hat Linux 3.2.2-5)) #3 SMP Sun Aug 10 19:37:59 EDT 2003
[root@elbmin3 root]$
[5.] Output of Oops.. message
No Oops is generated by this. No error messages are generated at all,
as a matter of fact.
[6.] A small shell script or example program which triggers the problem
Step 1. Run linux on my crappy intel hardware.
Step 2. Plug in USB2 device.
Step 3. Weep over lost work.
Step 4. GOTO Step 1.
[7.] Environment
Not actually sure how to go about gathering relevent info, so I'll
continue to follow the directions.
[7.1.] Software (add the output of the ver_linux script here)
This is my system running the 2.4.X kernel. I assume that most of the
info doesn't change when a new kernel is built and used.
[root@elbmin3 scripts]# sh ./ver_linux
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
