And so, on Jan 4th, the check was performed on one system now running under Ubuntu Intrepid, with kernel 2.6.27-9-generic, module ahci, driving Intel Corporation 82801GR/GH (ICH7 Family) SATA AHCI Controller (rev 01) (8086:27c1). Lockups were still reported. CPU was stuck for 61s. In the reported stacks, there always were lines :
[<c037e5eb>] ? _spin_lock_irq+0x1b/0x20 [<f886c8f6>] raid1d+0xb6/0x3e0 [raid1] above that, the stack content was varying. Other two systems I mentioned initially are now controlled by another person so I could not give further reports from these. The system with ata_piix mentioned in comment #9 had been disassembled. The system with AMD/NForce/ahci mentioned in comment #15 still runs under 2.6.24-22-generic (Hardy) and does not report any lockups on monthly data-checks. So I feel this is related to Intel SATA/ahci interaction. -- RAID1 data-checks cause CPU soft lockups https://bugs.launchpad.net/bugs/212684 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
