PROBLEMS: computer crash due to overfilling ramfs; iso9660 CD not read correctly

----- Begin Hush Signed Message from [email protected] -----

hello.
i just compiled a 2.4.0 kernel from stable sources from ftp.us.kernel.org,
including reiserfs support from the reiserfs patch (www.namesys.com) .
anyway, i compiled the ramfs (resizeable ramdisk) feature as a module, loaded the module, and mounted a directory and started copying. i kept copying files onto it via 'cp' and after each copy, i would check the ram left using 'top'. everything was fine until i had 500kb of ram left and i copied a 2mb file. total freeze. the only thing that would happen is my keystrokes would output to the screen, and i could also use ALT + F? to change terminals.
i used the reset button and everything was back to normal. i don't know
why that happened.
my next problem is with data CD's (iso9660). I had the same problem with 2.2.x kernels. after mounting the data CD, it would list fine, but the data would be corrupted (BMP and TIFF images would appear with lines through them, sometimes not even recognized as images; mp3's would sound like they are combined). the solution would be to 'umount' the directory, open the cd-rom a little, and close the tray. after 'mount'ing it, hopefully it would be fine. if not, just pop the drive open again, etc. until it worked. the distribution is slackware 7.1, but most of my software is hand-compiled.
i read the REPORTING-BUGS file, and here is some of system info ( i hope
it isn't overkill; i'm sorry if it is):

I faced the same problem when I patched 2.4.0test7 with reiserFS support. On my further correspondence with Alan Cox, he wrote that he is unwilling to listen about any "bug report for 2.4kernel", arising after patching kernel with some foreign code...

Any comments?

Archan Paul rearranged electrons thusly:

Simple comment: you misplaced the "quotes". If you use third party patches (and reiserfs, though fairly mainstream, _is_ a third party patch), you have to ask the patch maintainer. ReiserFS is not (as far as I know) part of the linux kernel yet.
