sane-hp crashes when there are USB errors
Last modified: 2007-11-30 17:10:51 EST
Description of problem:
Having persuaded sane that my USB scanner existed it then segfaults
(hp driver) with segfault at 0000000000000010 rip 000002a95688ffe error 4
Changing arch to x86-64... does this happen on x86 too?
I've not seen it occur on the x86-32 box yet
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.
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.
Please attach what you have. Thanks.
The logged segfault is all I have (its from dmesg segfault logging by
Alan, I don't even know what application you're running. :-)
Try setting SANE_DEBUG_HP=255, and run 'scanimage'.
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.
Without debug info it's hard to say very much about this.
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.
