Hello, I'm trying to get stable kernel for Promise SuperTrak X16350 hardware. So far 2.6.20, 2.6.21 and 2.6.22 oopsed like this (while doing rsync): kernel BUG at block/elevator.c:366! invalid opcode: 0000 [1] SMP CPU 1 Modules linked in: softdog sch_sfq forcedeth ext3 jbd mbcache dm_mod xfs scsi_wait_scan sd_mod stex scsi_mod Pid: 1139:#0, comm: xfsbufd Not tainted 2.6.22.5-0.2 #1 RIP: 0010:[<ffffffff8033f5da>] [<ffffffff8033f5da>] elv_rb_del+0x3a/0x40 RSP: 0000:ffff8100759b1c00 EFLAGS: 00010046 RAX: ffff81000d1f5428 RBX: ffff81000d1f5428 RCX: ffff81007c1a1a00 RDX: 0000000000000000 RSI: ffff81000d1f53b0 RDI: ffff81007c102af0 RBP: ffff81000d1f53b0 R08: ffff81004a9dab50 R09: 0000000000000000 R10: 0000000000000000 R11: ffffffff880072c0 R12: ffff81007c102ac0 R13: ffff81007c1a1a00 R14: 0000000000000004 R15: ffff81007c102b18 FS: 00002ba2cafc9be0(0000) GS:ffff81007d0a5b40(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 00002ba2cab5a158 CR3: 000000003c5ce000 CR4: 00000000000006e0 Process xfsbufd (pid: 1139[#0], threadinfo ffff8100759b0000, task ffff81007cac1040) Stack: 0000000000000001 ffff81007c102ac0 ffff81000d1f53b0 ffffffff8034abe8 0000000000000246 ffff81000d1f53b0 ffff81007c1a1a00 ffff81007c102ac0 ffff81007c0f2d08 0000000000000004 ffff81007c102b18 ffffffff8034ad55 Call Trace: [<ffffffff8034abe8>] cfq_remove_request+0x78/0x1b0 [<ffffffff8034ad55>] cfq_dispatch_insert+0x35/0x70 [<ffffffff8034b61f>] cfq_dispatch_requests+0x1bf/0x3a0 [<ffffffff8033f11f>] elv_next_request+0x3f/0x150 [<ffffffff80243b04>] lock_timer_base+0x34/0x70 [<ffffffff88007329>] :scsi_mod:scsi_request_fn+0x69/0x3d0 [<ffffffff80343d46>] __make_request+0xe6/0x5d0 [<ffffffff8034158b>] generic_make_request+0x18b/0x230 [<ffffffff8034438a>] submit_bio+0x5a/0xf0 [<ffffffff8808d1e9>] :xfs:_xfs_buf_ioapply+0x199/0x340 [<ffffffff8808e099>] :xfs:xfs_buf_iorequest+0x29/0x80 [<ffffffff88092fbb>] :xfs:xfs_bdstrat_cb+0x3b/0x50 [<ffffffff8808e3c2>] :xfs:xfsbufd+0x92/0x140 [<ffffffff8808e330>] :xfs:xfsbufd+0x0/0x140 [<ffffffff8024fa3b>] kthread+0x4b/0x80 [<ffffffff8020b0a8>] child_rip+0xa/0x12 [<ffffffff8024f9f0>] kthread+0x0/0x80 [<ffffffff8020b09e>] child_rip+0x0/0x12 Code: 0f 0b eb fe 66 90 48 83 ec 08 49 89 f8 48 89 f8 31 c9 eb 09 RIP [<ffffffff8033f5da>] elv_rb_del+0x3a/0x40 RSP <ffff8100759b1c00> I can reproduce it without bigger problem. Here are the same oopses on 2.6.20: http://paste.stgraber.org/3138 This is 1 x dual core athlon64 on asus m2npv mainboard, 2GB RAM. There is hw raid on fasttrack 16350 only (no software one). Has anyone seen this ? Going to try without cfq. -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/ - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
