Hi, fellow linuxers!

Here is kernel oops, I've got running my long-running computational
program (am1), which uses smbfs mounted disk:

Unable to handle kernel paging request at virtual address c2846025
current->tss.cr3 = 00424000, cr3 = 00424000
*pde = 0009e067

It happends approx. once a day. Already 5 oopses collected,
all of them are the same.
After that all programs accessing smbfs mounted directory hang.

System: linux 2.0.27 with applied latest smbfs patch running on
Cyrix P133+ with 32 Mb of RAM. A lot of swap space present.

Any hints?
