Oops with 2.2.3

The first time the machine got unusable was after the first oops.
I was patching my 2.2.3 source tree with the 2.2.4 patch.
The source tree was on a local ext2 partition on a SCSI disk
(aic7xxx), and the patch came from a Solaris NFS server.
The second time I had to reboot it was when I got endless
VFS: grow_buffers: size = -1779891135
messages. (that was during compilation of the 2.2.4 tree)
