When I use SATA disks heavily on a 5.3-R machine (Athlon) with the SiI3512 disk controller, I get frequent (sometimes one every 1-5 minutes) WRITE_DMA timed out messages (with different blocks and both disks). It also panics with more than one kind of panic, and sometimes doesn't even get to finish the background fsck from the previous panic before dying again. Given that both disks get the WRITE_DMA messages, and the one with the OS on did...

Hi, We're using gmirror on our sun fire x2100 and FreeBSD 6.1-p10. Some days ago I found this in the logs: Apr 1 02:12:05 x2100 kernel: ad6: WARNING - WRITE_DMA48 UDMA ICRC error (retrying request) LBA=612960533 Apr 1 02:12:05 x2100 kernel: ad6: FAILURE - WRITE_DMA48 status=51<READY,DSC,ERROR> error=10<NID_NOT_FOUND> LBA=612960533 Apr 1 02:12:05 x2100 kernel: GEOM_MIRROR: Request failed (error=5). ad6[WRITE(offset=313835792896, length=4096)]...

Hi, I have a problem, probably with the SiI 3512 SATA150 controller in a dual-Opteron IBM eServer 326: Every once a while the kernel issues a message like: ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=150190687 The system waits a few seconds and continues to work normally. It typically occurs several times a day most likely depending on the load of the (SATA connected) hard drive. We have two machines of the same hardware configuration, both with two hard drives...

...rg/~mr/dmesg.log.gz Root is on gmirror volume (2 SATA disks), a backup FS is on graid3 (5 firewire disks). This server acts as an bacula server. During backup with bacula I discovered an complete system freeze (no keyboard, nfs, disk...) after the following lines on the screen: ... ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=108916879 ad1: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=116030287 ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=108911183 ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=108378767 Since I could ping the system and after waiting a...

Any suggestions? Thanks, Peter

Rarely, a geli partition I have freezes a process in bufwait state. It occurs after an ATA timeout message: Aug 5 03:47:13 thor kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=219028637 The geli partition resides on an Intel MatrixRAID RAID1 mirror using the ICH9R chipset (Asus P5K-E/WIFI). Killing (even -9) the process does not work. Rebooting is the only solution, yet the system is unable to flush the buffers and complete a clean unmounti...
