knoppix 5.0 toram swap and oops

[kaspare]

Hi,

I booted knoppix cd v5.0 toram with 1G of ram and 352M of swap.

I mounted a clean ext2 partiton (4,5 G) and did a search ( find . -exec grep -lsi 'passwd' {} \; ) the system hung and I lost the control. I had to ctrl sysrq s and u and b.
The free swap was 270M and the memory 12M, the cpu load 60%.

Then I did the same but NOT in toram mode and all was fine: no oops!

The I did the same but with toram + NOSWAP and all was fine

__________________________________________________ ________________

I made a minicd based in the 5.0 version with the 2.6.28 kernel, the cd is only 220M.
If I boot my minicd and do the same search I have the same behaviour: oops with toram and swap on, fine with toram without swap, fine with not toram with or without swap.

Any clue?

Cheers

Max

......no clues?
Anybody with the same problem? or I am the only one?

Please can you test it:

mount -o ro /dev/hdx /media/hdx (it's a safe read only mount..)
find /media/hdx | xargs grep -lsi passw (some stress...)

and let me know if there is a kernel oops.

Thanks

Max

I've done others tests:

booted with failsafe and "no-to-everything" (see knoppix cheatcodes..) with nounionfs (I modified the startup script): same results, oops with swap, ok without!!!
