Summary: [grub2] grub-mkrescue causes machine to reboot Project: GNU GRUB Submitted by: fixkowalski Submitted on: Wed 24 Jun 2009 12:18:20 PM GMT Category: Booting Severity: Major Priority: 5 - Normal Item Group: Software Error Status: None Privacy: Public Assigned to: None Originator Name: Francois-Xavier Kowalski Originator Email: fix.kowal...@gmail.com Open/Closed: Open Discussion Lock: Any Release: 1.96 Reproducibility: Every Time Planned Release: _______________________________________________________ Details: Hardware: - HP Mini 1000 - Boot device: USB key or SD-card Procedure: % ./configure && make && make install [...] % .grub-mkrescue --image-type=floppy rescue.img [...] # dd if=`pwd`/rescue.img of=/dev/mmcblk0 bs=1M 1+1 records in 1+1 records out 1474018 bytes (1.5 MB) copied, 0.179898 s, 8.2 MB/s Then boot on the SD-card using [F9] key. The machine starts loads something & reboot (return on BIOS screen). No error message is visible. Troubleshooting: It seems that this always happens when core.img includes an actual memdisk. Whether the memdisk image is generated by "cpio -o" or "tar -cf" does not change this. Booting without an included memdisk image (without the -m parameter of grub-mkimage) but with the memdisk, loopback & cpio modules works: It allows to manually examine the memdisk image file content, which is Ok. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?26875> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org http://lists.gnu.org/mailman/listinfo/bug-grub
