Hi, I am using xandros 1.0 ( 2.4.19-x1 according to xandros people this is nearly the same as 2.4.19 ). Everytime i try to mount any of my 2 scsi cdroms, i get a segmentation fault. Nobody has giving me any inside in the issue and i can't find the reason. The oops rapport tells me that the error has something to do with the "serial.o" module. What has mounting of cdroms to do with serial.o ? I am using aha152x driver. But there everything looks ok. Oops output: ksymoops 2.4.5 on i686 2.4.19-x1. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.19-x1/ (default) -m /boot/System.map-2.4.19-x1 (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options. Error (expand_objects): cannot stat(/modules/reiserfs.o) for reiserfs Error (expand_objects): cannot stat(/modules/splashFXmod.o) for splashFXmod Error (pclose_local): find_objects pclose failed 0x100 Warning (compare_ksyms_lsmod): module bsd_comp is in lsmod but not in ksyms, probably no symbols exported Warning (compare_ksyms_lsmod): module ppp_async is in lsmod but not in ksyms, probably no symbols exported Warning (compare_ksyms_lsmod): module ppp_deflate is in lsmod but not in ksyms, probably no symbols exported Warning (compare_ksyms_lsmod): module ppp_generic is in lsmod but not in ksyms, probably no symbols exported Warning (compare_ksyms_lsmod): module slhc is in lsmod but not in ksyms, probably no symbols exported Warning (map_ksym_to_module): cannot match loaded module reiserfs to a unique module object.
