hmm, OK that's a reasonable-looking hardware lineup. Often, weird crashes correlate with crufty, dusty old p200 boxen. The via chipset and udma _may_ be a problem - I'm afraid I haven't tracked that saga very closely. So hmmm. Your December 11 reports was *exactly* the same. Down to the same blockgroup number. Could you please run dumpe2fs -H /dev/hdd2 and let's see if we can work out the actual block which was being freed. (hmm, dumpe2fs doesn't display s_first_data_block).
