Well, I watched the number of files in /lost+found grow every time I
had to pull the plug from my HP C200, so I added a 'sync' option in
/etc/fstab and tried to get reiserfs working.
I patched my 2.4.9-pa13 kernel with
endian-safe-reiserfs-for-2.4.8.patch
which went without warnings or errors. A patched
reiserfs-progs-3.x.0k-pre9 also built well (despite what the configure
scripts says, you _need_ automake).
Creating a reiserfs-partition went without a hitch.
running bonnie -s 128 on it did this:
Adding Swap: 1041400k swap-space (priority -1)
eth0: Setting half-duplex based on MII#1 link partner capability of 0021.
reiserfs: checking transaction log (device 08:03) ...
Using r5 hash to sort names
ReiserFS version 3.6.25

which makes the error somewhere around here in
fs/reiserfs/namei.c, function reiserfs_add_entry, after call to
padd_item, before call to reiserfs_find_entry:
/* copy name */
memcpy ((char *)(deh + 1), name, namelen);
/* padd by 0s to the 4 byte boundary */
padd_item ((char *)(deh + 1), ROUND_UP (namelen), namelen);
/* entry is ready to be pasted into tree, set 'visibility' and 'stat data in entry' attributes */
mark_de_without_sd (deh);
visible ? mark_de_visible (deh) : mark_de_hidden (deh);
/* find the proper place for the new entry */
memset (bit_string, 0, sizeof (bit_string));
de.de_gen_number_bit_string = (char *)bit_string;
retval = reiserfs_find_entry (dir, name, namelen, &path, &de);
And there I'm stuck. I'm sending this to the parisc-list to document the
failure, and to linux-kernel to reach some reiserfs-experts, perhaps.
I'm willing to test anything!
Good luck,
Jurriaan
