Thanks Lonnie for the quick feedback ...
Regarding you points in your message ....
1) net5501 using comBIOS 1.33c
I had version 1.33 ... just did an update to 1.33c
Before proceeding to the other items, I did my tests again, and I
could re-create the bad fsck failure ...
Hence, not likely the BIOS as a source of the problem.
2) Sandisk 1 GB CF card (older blue/red label CF, what I had installed)
I have various 2GB and 8GB cards
3) "cat /proc/cmdline" shows libata.dma=5 which enables DMA for CF,
initially set with "set-kcmd libata.dma=5"
My cmdline is as follows:
root=/dev/ram0 rw init=/linuxrc astimg=astlinux-1.1.4.run
astlinux=net5501 astkd=auto asturw=auto astlive libata.dma=3
console=ttyS0,19200n8
I have changed libata.dma=5 ... but still was able to get the bad
fsck issue. Strange ...
Small side note: This image has console with 19200 baud
... different from other images (eg. Alix image starts at
38400) ... not a biggie
4) At initial setup, I use "separate" partitions for ASTURW (/dev/sda2) and
ASTKD '/mnt/kd/' (/dev/sda3) .
I was thinking of this also. But I had previously tried this on a
board (before applying 1) and 3) ) but still saw the bad fsck issue. (it
would fail on /sda2 ... not /sda3)
But I will proceed to re-test using the dual partitions, and let you
know how that goes.
What is your reasoning behind using dual partitions ?
---------------------------
Still curious about ext3 ...
Seems to be some previous code support in Astlinux for it.
My thinking on this comes from articles such as
http://www.embeddedarm.com/about/resource.php?item=459
Linux offers many filesystems, but we have been able to expose bugs in
most of them in at least some kernel versions.
The only one we have complete confidence in is ext3.
When in doubt, ext3 should be used for any partition that will be
mounted read-write.
The ext2 filesystem is much more fragile.
It is a perfectly good filesystem for systems that are able to mount it
read-only, or unmount it correctly.
But our experience shows that corruption is extremely likely with a
power failure on ext2.
