Kernel oops of crash.
This is with 2.4.9-7 ? We released an update kernel which has, amongst other things, a null pointer derefence in usb cameras fixed.... The version is 2.4.9-13.. Thanks for the oops trace, what about EIP? I cannot find it in the trace. Is in process_iso? Another thing that you can do is to download this: ftp.redhat.com:/pub/redhat/linux/rawhide/i386/RedHat/RPMS/kernel-2.4.13-0.3.i386.rpm It should work. I installed the 2.4.9-13 kernel and that helped, thanks! About the EIP, I can't find it. The kernel crashed real hard, so the only way for me to get some info was by typing at the console $cat /dev/video0 > /dev/null Then the kernel messages started coming on screen, but only the end stays visible. I think the EIP must have scrolled of screen. If you have any ideas to get it in an other way, please tell me, I am willing to crash my system ones more;) It seems to be the case of infamouse list_del() in usb-uhci - list_del (p); + p_tmp = p; p = p->next; + list_del (p_tmp); delete_desc (s, desc); It went into Linus tree at 2.4.10, so I thought that 2.4.7-ac would not be vulnerable. But apparently it was. I was too hasty with the Rawhide, we do have an update out which fixes the problem within the 7.2 trunk. ftp://ftp.redhat.com/pub/redhat/linux/updates/7.2/en/os/kernel-2.4.9-13.i386.rpm I just verified that it does contain the fix (actually, I checked out the kernel_2_4_9-13 branch) |
