HP DL145 G2 completly unstable under SUSE SLES 9 SP2
The problem is directly related to moderate or heavy network I/O that involves reading from, or writing to disk.
I have updated my servers to the latest SATA firmware, the latest LOM firmware, and the latest BIOS firmware. I'm also using the BCM5700 ethernet driver from SUSE, the bcm5700-8.13.3a-1.
The only log errors generated, are sent to console, and look like these :
hde: dma_timer_expiry: dma status == 0x24
When the crash occurs, the server responds to pings, and tcp sockets remain open. It will keep spewing out the dma_timer_expiry logs, but nothing else really works.
Right before the crash, watching vmstat, all processes are shown to move into wait state.
Our operating environment is:

Does Novell actually mean anything when they "YES Certify" hardware, or is that a big marketing lie? Sles9 is completly unstable on these boxes. My customers running Debian have never crashed.

Re: HP DL145 G2 completly unstable under SUSE SLES 9 SP2
I bought this hardware combination because hey, Novell said it worked on this specific platform according to YES certification. HP's certification matrice agreed to this.
This is a vendor problem. Where the is the Vendor in trying to fix this? Where is the best practices document that will tell me what I'm doing wrong?
No wonder both Novell and HP are in dire financial straights. This is why Dell is hurting. Treat your customers right, and they'll treat you right. Treat them wrong, and they'll find a new vendor.
