Hardware: AMD Athlon64 with 32bit install of FC5t3 Installed OK, booted to rescue environment with "linux rescue selinux=0" and did "yum install mkinitrd" and rebuilt initial ramdisk to fix dmraid problem. Ran through the firstboot setup and disabled SELinux, rebooted. Switched to runlevel 3 and as root ran: "yum -y update" It downloaded lots of packages, started the transaction test and Segfaulted. This was repeatable. I tried just using the rpm command to manually update the kernel. Here are the results (Is this a known problem? Worth filing?): Preparing... ########################################### [100%] 1:kernel ########################################### [100%] *** glibc detected *** /sbin/grubby: munmap_chunk(): invalid pointer: 0xbfd63d90 *** ======= Backtrace: ========= /lib/libc.so.6(__libc_free+0x17b)[0xc0a3ef] /sbin/grubby[0x804fd12] /sbin/grubby[0x804fe73] /sbin/grubby[0x8050c9e] /lib/libc.so.6(__libc_start_main+0xdc)[0xbb87a4] /sbin/grubby[0x804a001] ======= Memory map: ======== 00557000-00570000 r-xp 00000000 fd:04 5630609 /lib/ld-2.3.90.so 00570000-00571000 r-xp 00018000 fd:04 5630609 /lib/ld-2.3.90.so 00571000-00572000 rwxp 00019000 fd:04 5630609 /lib/ld-2.3.90.so 00a6b000-00a6c000 r-xp 00a6b000 00:00 0 [vdso] 00ba3000-00cc6000 r-xp 00000000 fd:04 5630616 /lib/libc-2.3.90.so 00cc6000-00cc9000 r-xp 00122000 fd:04 5630616 /lib/libc-2.3.90.so 00cc9000-00cca000 rwxp 00125000 fd:04 5630616 /lib/libc-2.3.90.so 00cca000-00ccd000 rwxp 00cca000 00:00 0 00df8000-00e03000 r-xp 00000000 fd:04 5630594 /lib/libgcc_s-4.1.0-20060214.so.1 00e03000-00e04000 rwxp 0000a000 fd:04 5630594 /lib/libgcc_s-4.1.0-20060214.so.1 08048000-08089000 r-xp 00000000 fd:04 2553628 /sbin/grubby 08089000-0808c000 rw-p 00041000 fd:04 2553628 /sbin/grubby 0808c000-08094000 rw-p 0808c000 00:00 0 0832e000-0838b000 rw-p 0832e000 00:00 0 [heap] b7f5b000-b7f5c000 rw-p b7f5b000 00:00 0 b7f66000-b7f67000 rw-p b7f66000 00:00 0 bfd51000-bfd67000 rw-p bfd51000 00:00 0 [stack] /sbin/new-kernel-pkg: line 89: 3707 Aborted /sbin/grubby --add-kernel=$bootPrefix/$kernelName-$version $INITRD --copy-default $makedefault --title "$title" ${mbkernel:+--add-multiboot="$mbkernel"} ${mbargs:+--mbargs="$mbargs"} --args="root=$rootdevice $kernargs" --remove-kernel="TITLE=$title" -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
