Details:
I'm running Mach/Hurd in qemu/kvm, on a Linux 4.4.0 host (Ubuntu 16.04). Mach
is 1.7+git20160607-486-dbg; the Hurd is from debian-hurd-20160325.
I always get panics when I run update-grub:
ext2fs: /dev/hd0s2: panic: main: device too small for superblock (1024 bytes)
/hurd/fatfs: Invalid number of bytes per sector
/hurd/crash: /hurd/iso9660fs --ro /dev/hd0s2(1432) crashed, signal {no:11,
code:1, error:1}, exception {1, code:1, subcode:241664}, PCs: {0x804aa5c,
0x11254fc, 0x11254fc, 0x10ccb10, 0x10ccb10}, killing task.
Here's what update-grub is reporting:
root@debian:~# update-grub
Generating grub configuration file ...
Warning: Requested serial terminal but GRUB_SERIAL_COMMAND is unspecified.
Default parameters will be used.
Found GNU Mach: /boot/gnumach-1.6-486.gz
Found GNU Mach: /boot/gnumach-1.7-486-dbg.gz
Found Hurd module: /hurd/ext2fs.static
Found Hurd module: /hurd/exec
done
root@debian:~#
/dev/hd0s2 is the extended partition:
Device Boot Start End Sectors Size Id Type
debian-hurd-20160325.img1 2048 5787647 5785600 2.8G 83 Linux
debian-hurd-20160325.img2 5789694 6143999 354306 173M 5 Extended
debian-hurd-20160325.img5 5789696 6143999 354304 173M 82 Linux swap /
Solaris
Looks to me like it's doing something to the extended partition, which seems
strange, and then bad things happen.
