CF problem: assuming drive cache: ...

phantom_cyph · 06-12-2008, 12:13 AM

I customized a very minimal Ubuntu (the 9.0mg iso) system on my 2Gb Compact Flash card. The system is blazing fast when its up, but its really kinda strange in 2 ways:

1. after booting GRUB, the "cursor" just blinks for like 5 minutes (or more)

2. after the 5 minutes is up, it actually boots in like, 20 seconds, but not before I get this message:

Code:

Assuming drive cache: write through

Here is my /etc/fstab (no, I didn't write it...)

Code:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# /dev/sda1

# /dev/sda5

/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec 0       0
/dev/scd1       /media/cdrom1   udf,iso9660 user,noauto,exec 0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec 0       0

Now, this error is all over the net, and I couldn't find a solution, just about 30-40 pages with people sending in the problem, with no response. So hopefully I get a response

Thanks in advance!

Hi I've used cf a lot in development and have had exactly the same problem sometimes. For me it came down to the type of reader used, some readers just caused the hang others didn't. I think its something to do with DMA, it just won't sync for ages on boot.
So I'd say try another reader or a USB one if it's built into your system.
