Description:
With atapi-cam.c (rev 1.42.2.3) when running k3b application, system
completely hangs on k3b splash screen and I had to use power button only
to restart the machine.
Extremely strange. I can't offer any definite solution at this point,
since I have no idea how this change could cause a system to hang. Here
are a few possible investigation ideas:
* AFAIK k3b is just a front-end for command-line tools. You should
determine what exact commands are spawned by k3b to identify which of
these is causing the apparent hang;
* it would also be useful to enable CAM debugging options (see
"man 4 cam", option CAMDEBUG, and flags CAM_DEBUG_TRACE and
CAM_DEBUG_SUBTRACE) and to capture all console output up to the hang
(for example using a serial console)
* if Scott's hunch of an interrupt storm is correct, then this issue
might be related to the DMA problem described under PR 103602, so
it would be useful to try the last patch I sent on that PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=103602&getpatch=12
* if all else fails, please let me know if the attached patch, which
reverts part of rev. 1.42.2.3, changes anything.
I tried your attached patch and the problem is still the same. System
hangs when starts k3b.
With atapi-cam.c rev. 1.42.2.2, k3b starts fine, system doesn't hang.
For your information I have k3b normal startup messages with atapi-cam.c
rev. 1.42.2.2.
It might help to find the problem.
