Description Alan Cox 2004-10-09 14:53:00 EDT

Description of problem:

Having persuaded sane that my USB scanner existed it then segfaults
(hp driver) with segfault at 0000000000000010 rip 000002a95688ffe error 4 

HP 6200C

Comment 1 Bill Nottingham 2004-10-11 10:54:01 EDT

Changing arch to x86-64... does this happen on x86 too?

Comment 2 Alan Cox 2004-10-11 10:55:07 EDT

I've not seen it occur on the x86-32 box yet

Comment 3 Tim Waugh 2004-10-12 09:05:56 EDT

Is there a stack trace?  What SANE-aware application are you using?

Try setting SANE_DEBUG_HP=255 to see if there's more information we
can get prior to the crash.

Comment 4 Alan Cox 2004-10-12 09:20:41 EDT

I didn't get a trace (was just the log). I've had a play with this and
I found out a lot more. It only crashes using USB, it only crashes
when the USB logs a collection of failures. Looks like its some kind
of intolerance to errors.

It isn't a 32/64bit problem - I just happened to use SCSI on the 32bit.

Comment 5 Tim Waugh 2004-10-12 09:57:54 EDT

Please attach what you have.  Thanks.

Comment 6 Alan Cox 2004-10-12 10:07:14 EDT

The logged segfault is all I have (its from dmesg segfault logging by
the kernel)

Comment 7 Tim Waugh 2004-10-12 10:21:34 EDT

Alan, I don't even know what application you're running. :-)

Try setting SANE_DEBUG_HP=255, and run 'scanimage'.

Comment 8 Alan Cox 2004-10-12 10:23:50 EDT

It ws running "xsane" when it crashed. Its now plugged into a
production system via scsi so the earliest I can try USB again is
probably late october.

Comment 9 Tim Waugh 2004-10-12 12:46:25 EDT

Without debug info it's hard to say very much about this.

Comment 10 Matthew Miller 2006-07-10 19:37:40 EDT

Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.

Thank you!
