SABRE0 errors in dmesg
Hi there,
I'm here to bug you again :)
While I was doing a bit of debug to know what's going wrong with my system, I
found strange entries in dmesg regarding SABRE0.
I saw that once someone submitted a post on this topic, and was asked for
details, so I want to add my own two cents in addressing this issue:
I was trying to view a movie (with Mplayer and SDL support) while dmesg got
filled up with messages like this:
sys32_ioctl(mplayer:1817): Unknown cmd fd(3) cmd(8004700c) arg(00000400)
SABRE0: Uncorrectable Error, primary error type[DMA Read:Translation Error]
SABRE0: bytemask[00ff] dword_offset[2] was_block(1)
SABRE0: UE AFAR [00000000107832d0]
SABRE0: UE Secondary errors [(none)]
SABRE0: IOMMU Error, type[Invalid Error]
SABRE0: IOMMU TAG(9)[RAW(0000000000c6065a)error(Invalid
Error)wr(0)sz(8K)vpg(c0cb4000)]
SABRE0: IOMMU
DATA(9)[RAW(000000006fe00000)valid(1)used(1)cache(0)ppg(0000000000000000)
When using the box for other tasks (browsing the Web, compling a kernel,
playing mp3s) dmesg output is absolutely clean.
I'm using 2.4.21 (debian), but it smells like 2.4.18 (also debian stock) was a
little faster in disk i/o, according to hdparm. My hard drive controller is a
CMD646 "multiword dma limited" (shame on that), while my hard drive is custom
Maxtor 40Gb.
