Hi, I hope this is the right mailing list, I think this is an ext3 error. I was copying a bunch of largish files around last night (between 300MB and 5GB each), and suddenly the partition I was copying to stopped responding - any program accessing files on that partition would lock up, and not even kill -9 would terminate them. I'm not particularly experienced with tracking down problems like that, but I did find this at the end of dmesg's output. I'm running kernel 2.4.18, so I'm wondering whether this bug has already been fixed? If not, I can supply more information, but apart from version numbers I'm not sure what else I could find out. Anyway, here's the output, please let me know if it means anything to anyone! Thanks, Adam.
