boot cache mode hangs on non-partitioned hard drive

Post in this forum for problems at boot time, if there was no problem for burning the disc. For example can't find the CD, or strange errors when you press enter at the very first prompt.

boot cache mode hangs on non-partitioned hard drive

Post by xerces8 » 14 Jul 2013, 16:22

Hi!

I boot sysrescd from a USB stick via GRUB4DOS using the following menu config:

Code: Select all

   kernel /boot/live/sysresCD/3.7.0/isolinux/rescue32 scandelay=1 docache  subdir=boot/live/sysresCD/3.7.0
   initrd /boot/live/sysresCD/3.7.0/isolinux/initram.igz
Today I noticed that this hangs later when is searches for sysrcd.dat file.

Before it worked on the same PC, then I did a badblocks -w /dev/sdb.
Badblocks wote a 0xaa pattern all over the sdb disk.

After that sysrescd hangs during boot, with the last line printed "Attempting to mount device: /dev/sdb".

Apparently the 0xaa pattern confuses the code (maybe one of the tried filesystems?).

For a rescue system this is a bad thing. I had to use RIPLinux instead.

Regards,
David

PS: This is using v 3.7.0

Yes, this is very bad.
A workaround is to add "skipmount=/dev/sdb"
