 In this mail:
 It was suggested to do a backtrace on it. I didn't have the option in 5.1-
 RELEASE, but I grabbed the 20030624 snapshot and was able to get the 
 following information.
 First of all the error seems slightly different, but the end result is the 
 same, unable to boot fully. First I get (the relevant parts IMO):
 pcib5: <ServerWorks host to PCI bridge(unknown chipset)> at pcibus 5 on 
 pci5: <PCI Bus> on pcib5
 ips0: <IBM ServeRAID Adapter> mem 0xf4000000--xf7ffffff irq 9 at device 3.0 
 on pci5
 ips0: failed to get configuration from device
 device_probe_and_attach: ips0 attach returned 6
 pci9: <PCI bus> in pcib9
 Memory modified after free 0xc18cd700(252)
 panic: Most recently used by devbuf
 Here's the trace:

 This machine is the 235, as we had to install linux on the 345 to get it into 
 production. I'm not sure how long I can do testing with this machine.
 Also, if someone knows how to report these backtraces without having to type 
 them in I would be appriciate a heads up on it. Thanks.
