It also seems that the timeout is related to a semaphore or locking problem: the freeze (or kernel panic) happens much faster if more than one process is accessing the disk; it happened twice in very short time when another machine was mounting the drive via nfs. The spin_lock kernel panic has been adressed in 2.6.11. The ata1 command timeout turns out to be related only to raid arrays composed of different drives; in particular a raid 0 pair composed of one 6Y200M0 and one 6B200S0. Arrays of identical disks alleviates this problem; the older 6Y2000M0 seems to be the source of it. |
Distribution: Fedora Core 3 Hardware Environment: ASUS A7N8X-E important: onbaord SATA controller Sil 3112A 1 GB RAM 4 Maxtors 200Gb in Raid 0+1 (software) Software Environment: mdadm raid 0+1 + lvm on top (bug has been reproduced without this raid setup) Problem Description: After copying about 200GB of data, there is either a kernel panic or a complete freeze with the message ata1: command timeout. Enabling on the hardware the Sil3112A (and loading the module) and moving over 2 drives to that controller causes the crash to happen earlier: after about 20GB of data copied over. No crashes happen using only the sil3112A controller and the sil_sata, only with promise_sata, and more rapidly when both were loaded. Once when we got the kernel panic it said: -not syncing: fs/jbd/transaction.c:978:spin_lock(fs/jbd/journal.c) already locked by fs/jbd/transaction.c:1553 and __journal_try_to_free_buffer was on top of the stack trace. Steps to reproduce: cp -ax from a large drive to another large drive. different scenarios that reproduced the bug: + 2 drives in raid0 on the sil3112A copying over to 2 drives in raid0 on SATA150Tx4 ata1:comand timeout after 20GB (independently of which port was used on the promise card) + 2 drives in raid0 on connector 1 and 3 of SATA150tx4 and 2 other drives in raid0 on 2 and 4, WITH the sil_sata module loaded in memory but with the sil3112A not present (hw disabled): ata1: command timeout after 60GB +same as above with only sata_promise loaded instead of both sata modules: after about 200GB. The msg is always ata1 :command timeout in all cases (except for once a kernel panic in this case) we used the same hardware minus the promise card for several months with drives on the sil_3112A on RH9 (latest updates: possibly 2.4.31) without any issues. here's what lspci -v returns (with the sil3112A disabled, and sil_sata not loaded) 00:00.0 Host bridge: nVidia Corporation nForce2 AGP (different version?)
