g_vfs_done error third part--PLEASE HELP!

[Willy Offermans]

Dear FreeBSD friends,

It is already the third time that I report this error. Can someone help
me in solving this issue?

Over and over again and always after heavy disk I/O I see the following
errors in the log files. If I force ar0s1g to unmount the machine
spontaneously reboots. Nothing seriously seems to be damaged by this
act, but anyway I cannot afford something bad happening to this
production machine.

Currently the error is the following:

<snip>
...
Apr 21 19:44:36 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725074944, length=2048)]error = 5
Apr 21 19:45:07 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725074944, length=2048)]error = 5
Apr 21 19:45:38 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725074944, length=2048)]error = 5
...
</snip>

before the error appeared like:

<snip>
...
Apr 18 20:00:15 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725072896, length=2048)]error = 5
Apr 18 20:00:46 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725068800, length=4096)]error = 5
Apr 18 20:00:46 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725072896, length=2048)]error = 5
Apr 18 20:01:17 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725068800, length=4096)]error = 5
Apr 18 20:01:17 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725072896, length=2048)]error = 5
Apr 18 20:01:48 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725068800, length=4096)]error = 5
Apr 18 20:01:48 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725072896, length=2048)]error = 5
Apr 18 20:02:19 sun kernel: g_vfs_done():ar0s1g[WRITE(offset=290725068800, length=4096)]error = 5
...
</snip>

I have no clue what the errors mean, since offsets of 290725068800,
290725072896, and 290725074944 seem to be ridiculous. Does anybody 
have a clue what is going on?

I'm using FreeBSD 7.0, but found the error being reported before with
previous versions of FreeBSD. I can and will provide more details on
demand.

Any hints are very much appreciated.
