errors

Hello,

I have a Dell Poweredge 2600 with a Perc3/Di containing a 100GB raid 0.
Frequently, anywhere from 1 to 4 days, the server can't write to disk
anymore and prints on TTY1:

EXT3-fs error (device sd(8,4)) in ext3_reserve_inode_write: IO Failure
I/O error: dev 08:04, sector 0
EXT3-fs error (device sd(8,4)) in ext3_new_inode:  IO failure
I/O error: dev 08:04 secotor 0
I/O error: dev 08:04 secotor 1050528
EXT3-fs error (device sd(8,4)): ext3_get_inode_loc: unable to read inode
block - inode=73040, block=131316
I/O dev 08:04 sector 0
EXT3-fs error (device sd(8,4)) in ext3_reserve_inode_write: IO Failure

and on and on, with a lot of sector 0's and other sectors, which numbers
seem to be random, as well as the inodes and blocks.  But, all of the
I/O errors are always from dev 08:04.  The server is
running the stock 2.4.20 kernel (hand compiled) and redhat 8.0 i386.  I
can reboot the server and i'll run again fine anywhere from 1-4 days until
this error happens again.  I upgraded to 2.5.66 as a test, and it gave me
a different error message after a couple of days.  I don't have that error
message written down, but the last line I do remember, which was
"AAAAAAIIIIIIEEEEEEEE! killing interrupt handler".  With 2.4.20 I can
still ssh into the server, but when I do any command, like df, iostat,
etc...it says "-bash: /bin/df Input/output error".  With 2.4.20 I can hit
the rest button, but with 2.5.66 the reset button doesn't work once the
box prints the error message on tty1, and I have to inplug the power
cables from back.  I can't ssh or ping it either.

Does anyone have suggestions I can try?  Downgrading the kernel to
older 2.4 versions still generates the same error.

			Thanks!
