Hi, I tried to benchmark some Linux filesystems but the kernel crashed when doing lots of mkdir's on a JFS filesystem. I did this on kernel 2.6.21-rc4-git1, so I'm not sure it's a JFS problem. The mkdir's were done in parallel by 2 forks.
Here's the dmesg: Bad page state in process 'mkdir' page:ffff810001b632c0 flags:0x4000000000000818 mapping:ffff810036385ca8 mapcount:0 count:0 Trying to fix it up, but a reboot is needed Backtrace: Call Trace: [<ffffffff802a7707>] bad_page+0x57/0x90 [<ffffffff8020b8a0>] free_hot_cold_page+0x60/0x130 [<ffffffff882b17ef>] :jfs:diWrite+0x50f/0x540 [<ffffffff882c162a>] :jfs:txCommit+0x1fa/0x1010 [<ffffffff882a944e>] :jfs:jfs_mkdir+0x26e/0x370 [<ffffffff8022e50f>] mntput_no_expire+0x1f/0xd0 [<ffffffff8020f1f4>] link_path_walk+0xd4/0xf0 [<ffffffff802bd0f9>] vfs_mkdir+0x79/0xd0 [<ffffffff802bd669>] sys_mkdirat+0xb9/0x130 [<ffffffff80267f8d>] error_exit+0x0/0x84 [<ffffffff80261c1e>] system_call+0x7e/0x83 ... The rest of dmesg is attached. It seems some lines at the end went missing (it's from a logfile). Greetings, Jasmin Buchert
