Our customer has a problem with dazuko. It causes kernel panic on Red Hat Enterprise Linux 3 with hugemem kernel. We manage to reproduce kernel panic in our end which probably means that it is not kernel configuration problem.
Kernel panic happens when our program tries to connect Dazuko. We get following error messages to our log: Dazuko error: writing to device: Bad address Kernel panic says that EIP is at dazuko_get_value and call trace have following symbols: linux_dazuko_device_write .rodata.str1.1 do_page_fault sys_write put_user_size linux_dazuko_sys_write sys_read do_page_fault Kernel panic output also has: Code: Bad EIP value. Kernel panic: Fatal exception The process is our on access scanner process. What worries me is that when googling hugemem I found a blog comment that said:"Incidentally, the 4G/4G patch had the nice side-benefit of exposing numerous bugs in the use of user pointers in drivers, most of which were quickly resolved." <http://www.orablogs.com/mt-bin/mt-comments271276.cgi?entry_id=1363> -- Juha Autero tel +358 9 2520 5108 Software Engineer fax +358 9 2520 5001 Linux Antivirus Solutions mobile +458 40 7429 483 F-Secure Corporation http://www.F-Secure.com BE SURE. _______________________________________________ Dazuko-devel mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/dazuko-devel
