[Pkg-sysvinit-devel] Bug#672959: kfreebsd-*: panic: vm_fault_copy_wired

[Carlos Alberto Lopez Perez]

severity 672959 serious
thanks
justification: unacceptable behavior on a production/stable system. renders the system unable to boot.


Hello,

This is a me-to report. Running Debian/sid kFreeBSD ADM64 on a virtual machine with qemu/kvm I unclean closed the machine (killed the qemu process when the machine was idle) and now the machine not longer starts.

When the init system reachs to "Checking root filesystems..." it gives a fatal error and the machine restarts itself (attached screen-shoot)

The machine keeps restarting itself in an infinite loop and there is no way to fix it.

Neither booting single-use mode (recovery mode) nor normal mode changes anything. As also neither booting kFreeBSD kernel version 9.0-1-amd64 nor 8.3-1-amd64 changes anything.

The machine has the following schema for its unique disk:

sysresccd ~ # fdisk -l /dev/sda

Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders, total 16777216 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00042061

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048    15988735     7993344   a5  FreeBSD
/dev/sda2        15990782    16775167      392193    5  Extended
/dev/sda5        15990784    16775167      392192   82  Linux swap / Solaris

sysresccd ~ # file -s /dev/sda1
/dev/sda1: Unix Fast File system [v2] (little-endian) last mounted on /, last written at Sat Jul 21 20:36:14 2012, clean flag 0, readonly flag 0, number of blocks 3996672, number of data blocks 3869351, number of cylinder groups 43, block size 16384, fragment size 2048, average file size 16384, average number of files in dir 64, pending blocks to free 0, pending inodes to free 0, system-wide uuid 0, minimum percentage of free blocks 8, TIME optimization


I tried fixing it booting the system with systemrescuecd but seems that the tool
fsck.ufs is not included on it.

Finally I was able to fix it by booting with the Debian/kFreeBSD AMD64 netinstall,
pressing next-next until reaching the partitioning dialog and then after
getting a shell with alt+f2 and running fsck.ufs /dev/ad0s1 the error goes
away.
