Hello
I am testing 2.6.5-rc1-mm2 and find it very slow when I do a bonnie test, also the system itself feels very sluggish. Looking at dmesg I get the following:
Badness in elv_remove_request at drivers/block/elevator.c:249 Call Trace: [<c028b28f>] elv_remove_request+0x8d/0x8f [<c02b6a4e>] scsi_request_fn+0x289/0x333 [<c028b174>] elv_next_request+0x3d/0xcb [<c028c8da>] generic_unplug_device+0x43/0x45 [<c02f1bfc>] md_unplug_mddev+0x32/0x34 [<c02f07e4>] make_request+0x22/0x29f [<c01a5523>] ext3_get_branch+0x4d/0xca [<c028ddc7>] generic_make_request+0xf2/0x165 [<c0138a41>] mempool_alloc+0x63/0x114 [<c011d42b>] autoremove_wake_function+0x0/0x38 [<c028dea6>] submit_bio+0x6c/0x11b [<c0154c42>] bio_alloc+0xba/0x182 [<c015355e>] block_read_full_page+0x19d/0x2a2 [<c01a5d77>] ext3_get_block+0x0/0x9e [<c0154cb3>] bio_alloc+0x12b/0x182 [<c01a5dcb>] ext3_get_block+0x54/0x9e [<c016d08e>] mpage_alloc+0x25/0x8a [<c016d3b8>] do_mpage_readpage+0x24b/0x314 [<c0246894>] radix_tree_node_alloc+0x10/0x4d [<c0246b00>] radix_tree_insert+0xdd/0xfd [<c0135dfa>] add_to_page_cache+0x5a/0xd5 [<c016d59b>] mpage_readpages+0x11a/0x15e [<c01a5d77>] ext3_get_block+0x0/0x9e [<c01a6a59>] ext3_readpages+0x0/0x15 [<c013bb8d>] read_pages+0x136/0x13f [<c01a5d77>] ext3_get_block+0x0/0x9e [<c0139a98>] buffered_rmqueue+0xf6/0x1d3 [<c0139c20>] __alloc_pages+0xab/0x2e0 [<c013be48>] do_page_cache_readahead+0xfc/0x165 [<c013c039>] page_cache_readahead+0x188/0x1d7 [<c01364f0>] do_generic_mapping_read+0xc9/0x38e [<c01367b5>] file_read_actor+0x0/0xca [<c0136a4c>] __generic_file_aio_read+0x1cd/0x1ff [<c01367b5>] file_read_actor+0x0/0xca [<c0136ac5>] generic_file_aio_read+0x47/0x61 [<c015031e>] do_sync_read+0x6f/0xa4 [<c011a214>] load_balance+0x3c/0x156 [<c01503fc>] vfs_read+0xa9/0xf5 [<c0150619>] sys_read+0x38/0x59 [<c034b8a6>] sysenter_past_esp+0x43/0x65
The system is a dual Xeon with HT enabled and 2GB memory. Bonnie is running on a software raid10 (six SCSI disks) with ext3.
It is compiled with CONFIG_SCHED_SMT and CONFIG_HIGHMEM4G. CONFIG_PREEMPT is not set. I can also post the full .config if necessary.
I get more of these badness messages when I boot.
Under 2.6.3 there are no problems. Also have tried 2.6.4-mm2 but that would oops during boot (when starting the SW raid).
