...problem. If a file write is in progress when invalidate_buffers() is called, I get an oops: [[[LVM is in the process of calling PV_FLUSH ioctl => invalidate_buffers()]]] Attempt to refile free buffer Unable to handle kernel NULL pointer dereference at virtual address 00000000 <kdb stuff> refile_buffer cleanup_transaction log_do_checkpoint log_wait_for_space start_this_handle journal_start ext3_file_write do_readv_writev sys_write The oops is from "*(char *)0 = 0" added by the ext3 patch, but I take it that trying to refile a free buffer is fundamentally a bad thing. The oops is caus...

I think I have this one solved, I hope. I think what Andreas and I are running into are a few different assertions. One being the LVM lvm_do_pv_flush caused assertion which is related directly to invalidate_buffers() being called which then triggers refile_buffer() on a journaled buffer, which appears clean in all other ways according to the checks in refile_buffer(). The following is what I've got in __invalidate_buffers() right now. if (!bh->b_count && !buffer_journaled(bh) && (d...

I have ext3 0.0.6b + 2.2.19 and cannot get ext3 to compile as a module. If I try to modularize it, or turn in off completely, the kernel build fails. Is there an easy fix for this, or is there something that I am missing? Thanks. Peter
