Hello,
last night i experienced a very strange behavior on a newly installed box
with a 9650 controller. sometimes the box hangs, and sometimes the tw_cli
isn't able to find the controller. in syslog there are lots of out of memory
errors freezing the whole machine. amazing is that we have two identical
boxes and it only happens on one box frequently.
we tried to set swiotlb=96 to the kernel module parameter in grub config as
i found this setting with DMA and io memory related problems one user
experienced, and the problem doesn't occur that often now. but the machine
is still unusable in an production environment.
i read your elder post and maybe we have the same problem?
The box also throws "Out of SW-IOMMU space ...on PIC devices" messages to
the console, thats why i googled and found this swiotlb param. The PCI
devices mentioned in the errors are:
03:00.0 RAID bus controller: 3ware Inc 9650SE SATA-II RAID (rev 01)
08:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1064ET
PCI-Express Fusion-MPT SAS (rev 04)
hope to find out why the 3ware controller isn't working with xen or what
the setting swiotlb is calculated end it it does the trick ...
