I have Debian 4.0r4a installation on a server with SAS1064E built-in controller: ~$ lspci | grep LSI 04:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS (rev 02) Vanilla kernel with aufs2-base5 patch: ~$ uname -a Linux ftp 2.6.28.7-aufs #10 Fri Mar 6 19:34:56 UTC 2009 i686 GNU/Linux There are six sata hard disks connected through SAS HDD Hub box to the controller on the motherboard by two sata cables. Everything work all right, but dmesg shows many annoying lines like this: [ 1876.212880] mptscsih: ioc0: attempting task abort!

Is this a firmware problem? In the mailing list archive I saw similar problem, but I don't sure. Thanks.
