Re: arcmsr + archttp64 calls dma_free_coherent() with irqs disabled - dmesg filled with warnings

2008-02-19 Thread Joshua Hoblitt
I have a test machine running:

0001-arcmsr-fix-message-allocation.patch
arcmsr-pci-alloc-consistent.patch
2.6.24-gentoo-r2

The arcmsr driver is loaded and archttp64 is running.  I've been access
archttp64 and there are no warnings in dmesg.  Without the patches this
would have generated 10s of MB of warning messages.  I haven't really
exercised the areca volumes yet but this looks to be both a fix for the
warnings and James' coding issues.  I'd vote for re-diffing and kicking
the patch upstream at this point.

Hi James,

Daniel took the time to patch up the 2.6.24 version.  I've tested it and
the warning messages are gone.  Please take a look at:

Re: difference between arcmsr (areca) 1.20.0X.13 & 2.6.20 in tree driver?

2007-04-10 Thread Joshua Hoblitt
The RAID card in question has reported an "SPD CheckSum Error" (bad
ram?) during system power on so it's looking like this is probably a
hardware or firmware problem and not a driver issue.
