ML350 frequent panics

Hi. Having purchased 2 ML350-G3 dual Xeon, w/Smart Array 641, 1GB RAM, and setup RedHat Enterprise 3.1, hangups and panics are common issue.
If servers are power cycled under dual processor, they might work fine for up to 6 days. Then kernel panic o black screen do occur. Either.
If any server is hard-reset (no power- cycling), it might work for up to 2 days w/o hanging or kernel oops.
Power cycling the servers as to get a prolonged life cycle suggests hardware misgiving.
Surprisingly, booting single processor kernel shows no problem, even thru prolonged usage (tested for 5 weeks OK).
All HP patches have been applied (kernel, Smart array). No HP monitoring/administration software is installed.
Usual message (when there is one) is "Kernel Panic. Fatal exception in interrupt handler - noy syncing - code 89 44 b1 18 8b 51 10 89 71 14 8d 42 ff 85 c0 89 41 10 74 34." or any of the sort.
Don't know what these numbers mean.
A custom patched kernel from RedHat wouldn't solve either. The only clue seems

Any help will be highly appreciated.

Federico:

There are bios updates to fix this problem:

You will need one diskette for this.

Let us know if this does not cure the Kernel Panic?

Enjoy!

Re: ML350 frequent panics

Thanks John for your prompt help.
In fact, the bios you suggest looks like same dated as the one I mentioned before, but I understand that look-alike does not mean same.
Let me a chance to download the patch you suggest and check for any difference. If different, I'll sure give it a try.
This was the case, news on my side won't come out before, lets's say, fifteen days now. Regards.

Re: ML350 frequent panics

Yeah... they are the same bios, except that the link I give you is for the diskette based version. I trust the diskette versions a bit more because the O/S does not get involved.

The syncing of the disk numbers you see are the O/S writing down the stuff it has in memory. Typical stuff.
Enjoy!

Re: ML350 frequent panics

Hi John. We've reopened the case with our local HP offices, and a new specialist came to announce that the RedHat supplied driver for the ML350 NICs is known to result in hangups of the kind we suffer when running in dual-processor schemes, under no specific load figures.
We're expecting to migrate the driver by Monday, so, if the patch should solve our nightmares, I expect to post the results.
