kernel 1.1.94, swap_free: swap-space map bad

kernel 1.1.94, swap_free: swap-space map bad

Post by Leland Ol » Tue, 28 Feb 1995 14:43:05



I got the following kernel error messages after intentionally loading
down my system: (kernel 1.1.94)

   ....snip....
VFS: Mounted root (ext2 filesystem) readonly.
Adding Swap: 15536k swap-space
swap_free: swap-space map bad (entry 00008000)
swap_free: swap-space map bad (entry 00008000)
VFS: Disk change detected on device 2/0
end_request: I/O error, dev 0200, sector 0
VFS: Disk change detected on device 2/0
   ....snip....
end_request: I/O error, dev 0200, sector 0
VFS: Disk change detected on device 2/0
end_request: I/O error, dev 0200, sector 0
Hmm.. Trying to use unallocated swap (00008000)
swap_free: swap-space map bad (entry 00008000)
swap_duplicate: trying to duplicate unused page
swap_free: swap-space map bad (entry 00004000)

Are the "I/O error" and "Disk change detected" a problem?  They
probably come from dosemu trying to boot from the empty dos A: drive.

I was getting similar swap_free error messages around 1.1.90-91, but
not under 1.1.92. (I didn't push that kernel as much in 92 either.)

I am no longer offered SELECTION as a kernel config option, and the old
selection program doesn't work with the kernel.

I'd be happy to provide more information if needed.

1. swap_free: swap-space map bad (entry 00002000)

What does it mean? I have got these messages since I installed linux
in my new computer (DX66 etc.) There is also following messages:

    Bad page table: [00CE26E8]=00002000
    swap_duplicate: trying to duplicate unused page

The kernel was 1.0.0. Now it is 1.1.12

fdisk shows

    Disk /dev/hda: 14 heads, 62 sectors, 768 cylinders
    Units = cylinders of 868 * 512 bytes

      Device Boot  Begin   Start     End  Blocks   Id  System
    /dev/hda1           2       2     234  101122   83  Linux native
    /dev/hda2         235     235     272   16492   82  Linux swap
    /dev/hda3         273     273     768  215264   83  Linux native

I also tried to redo my swap partition with the -c option (check for
bad blocks). No help.
