i have been experiencing hard locks (preceded by intense 5< load
averages, disk i/o timeouts, and processes gone astray) that seem to
be related to a possible bug in reiser4.
here is the information that i think is important:
a sample dmesg from right before a hardlock:

the partition in question is 232903996 kilobytes large (that's 223
gigabytes), and does not fail badblocks or fsck.reiser4 testing. my
system holds up to memtest86, and does not crash if the drive is not
mounted and used.
my question: can this be fixed, has it been fixed, or can i convert
this drive online to reiserfs.
sorry for such a long message, but this is very important to me. thank you!
