I'm having this issue on all of my servers running the linux-image-amd64 from the backports (2.6.32-bpo.5-amd64). I can't find a way to reproduce it, but i have one server that does a lot of fsync commands (mongodb) and i see if more often there as well. I also have a few servers with a stock kernel and they don't have those kind of errors at all. The reason i do use the kernel from backports is because i'm in need for the mpt2sas modules. [613954.220010] INFO: task mysqld:9935 blocked for more than 120 seconds.I do see similiar messages with mvsas and a tape drive. it's working with 2.6.32-bpo.4-amd64 but not with 2.6.32-bpo.5-amd64.
Hi,I have got on some servers (especially virtualized ones with VMware ESX) the same problem with this controller:
SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 01)
But the problem exists with Linux 2.6.{26,30,32}; so it may not be backports.org specific.
Those are webservers with apache, php and mysql; bad bad bad query design from the customer, if there is some additional I/O like a kernel upgrade, the whole server fucks up mostly..
