Hi,
I need some help figuring this one out. I cannot use git bisect and applying the 2.6.15-1 reiserfs4
patch does not work with newer 2.6.16 levels - looks like the mutex conversion hits it hard. Looking
in mm there are about 50 reiser4 patches...
To reproduce this problem I need reiser4 though the issue maybe in libata or scsi. Does anyone
have an idea how I can proceed to find what makes newer kernels get io errors which trigger a reiser4
panic? The panic is a zam-597 (fs/reiser4/txnmgr.c) with an rc=-5
Anyone have a git tree tracking linus with reiser4 patches applied staring before 2.6.15 - if so git
bisect could be used to find the change causing the problem.
One datapoint. In 2.6.15 + reiser4 2.6.15-1 works fine - the resiser4 filesystem is heavily used with
no errors. Smart report no problems with the drive being used. The libata driver used is sata_nv.
Please reply to my email - I am only subscribed to lkml.
Help!

ret = reiser4_write_logs(nr_submitted);
if (ret < 0)
reiser4_panic("zam-597", "write log failed (%ld)\n", ret);
