SubjectRe: Linux 2.6.0-test7 - Suspend to Disk success

Using -test8 I keep getting my bash killed, but there is more. It seems
that the sis900 driver got corrupted, since on resume my network card
works no more (NETDEV: transmit timeout...).

On resume I also get a lot of debug messages, this first excerpt is with
all modules loaded (alsa, ohci, ehci, ipv6, nfts, irda, yenta_socket)

You can see that:
note: bash[2312] exited with preempt_count 1

that causes the bash process to segfault.

Then here is the dmesg of a resume leaving only 2 modules (ipv4, md5),
that could not be removed.

--CUT-HERE-----CUT-HERE-----CUT-HERE-----CUT-HERE-----CUT-HERE---

I can send .config file on request. (this mail is just big enough).
