PROBLEM: log abort over RAID5



	Several people already reported this at linux-kernel and
elsewhere with no answers, I thought perhaps this would be a more
adequate forum...

[1.] One line summary of the problem:

	After I/O, journal is aborted and filesystems made read-only.


[2.] Full description of the problem/report:

	One can't anymore write to the affected file systems.  Upon
investigation, ext3fs journal was aborted and affected filesystems are
remounted read-only.  Reboot prompts for fsck to be run manually, with
fixes taking several prompts and minutes.


[3.] Keywords (i.e., modules, networking, kernel):

	File systems, I/O, RAID, LVM, kernel.


[4.] Kernel version (from /proc/version):

	Couldn't find /proc/version, uname -a gives:
Linux mercurio 2.6.2-1-686-smp #1 SMP Sat Feb 7 15:27:45 EST 2004 i686
GNU/Linux


[5.] Output of Oops.. message (if applicable) with symbolic information
     resolved (see Documentation/oops-tracing.txt)

	N/A


[6.] A small shell script or example program which triggers the
     problem (if possible)

	N/A


[7.] Environment
[7.1.] Software (add the output of the ver_linux script here)
