	huh... I'm using FreeBSD 4.3 from the CD.. no update/upgrade... 

>Description:
	
	When trying to write on a msdos partition, I get a kind of
kernel panic forcing a sync/reboot. 

>How-To-Repeat:
	

	I don't know if it's related to a hardware problem, but that
partition was on a Maxtor 40GB ATA-100 HDD. I'm using an Asus A7V
motherboard with Promise ata-100 chipset for this hard drive.

Heh by the way, sometimes I can see my cpu usage and sometimes no...
without touching anything on the kernel... 

>Fix:
	No idea...

 I noticed that this happens on an msdos fs with any kind of error. The fix
 is,
 of course, to either run Scandisk or fsck_msdosfs. There should be more
 'tolerance' for errors, though.

State-Changed-Why:  
What exactly are the commands you use? Please give an easy to reproduce 
case, preferably with an msdosfs on a floppy. What is "a kind of kernel 
panic"? Please specify the exact panic string. Better yet, read the FAQ 
on how to supply a kernel stack trace.

 HOW TO REPEAT:
 
 on my system with a maxtor 20G drive the following causes the system to freeze 
 within 1-5 attempts (seems to act like russian roulette):
 
 $ cp /usr/large.file.several.mbytes /dosd
 
 where /dosd has a fstab entry like:
 /dev/ad1s1              /dosd           msdos   rw              0       0
 
 upon reboot inspection of the copied file on /dosd reveals it up to be 
 incomplete, and sometime the copied file doesn't even get to be created 
 before the system froze
 
 Note: that was release 4.52 - I have moved to 4.6-RELEASE #0 recently and 
 don't know if any filesystem code has been updated between 4.52/4.6 I haven't 
 repeated the problem lately but that's probably becuase I've stopped writing 
 anything to msdos partitions.
