Hi Marc
Some more inputs I gathered on the scanpci issue are as follows:
1) scanpci () crashing is not consistent all the time. After removing my fix, and with the build procedure suggested by you, once it executed without system crashing, for a longer duration. But it was running for half an hour or so never ending, until I killed the process using Ctrl-c.
2) When I tried connecting remotely to the sparc, it never gave me a consistent output. The best last few lines that I could get are given below (and is got through the visual observation only).
pciGenFindNext: pciDeviceTag = 0x100f800, devid = 0xffffffff
pciGenFindNext: pciBusNum 256
pciGenFindNext: pciFuncNum 0
pciReadLong(0x100f800, 0)
pciGenFindNext: next bus
pciGenFindNext: pciBusInfo[257] = 0x891b0
pciGenFindNext: [257, 0, 0]
pciReadLong(0x1010000, 0)
This I got with a slight delay placed in pciReadLong () function within the ?if? condition. This delay was added by me to breath for some time to place the log output in the console.
