However, 2820SA turned out to have broken MSI support. Thus, in r254004 a quirk blacklisting MSI usage for that model has been introduced. There was also a similar report for 2230S, in which case it was unclear whether that type of controller or the motherboard is the culprit. To be on the safe side, MSIs also have been blacklisted for 2230S in said revision. This change has been MFCed down to releng/9.2, so it will be part of the final 9.2-RELEASE. However, it doesn't seem warranted to generally disable the use of MSIs in aac(4) again.

That could be due to MSIs being broken with your particular controller or mainboard. Please try whether setting the tunable hw.aac.enable_msi to 0 on the loader prompt before booting makes things work. If it does, please provide a verbose dmesg and the output of `pciconf -lcv`.

AAC regression in 9.2-BETA
I have an Adaptec 2820SA (SATA) controller that hangs the system during booting on 9.2-BETA[12]. The only message I see on the console refers to controller aac0 and indicates "TIMEOUT 138 SECONDS". This same controller/motherboard works flawlessly with 9.1-RELEASE-p5. I have moved this hardware to "testing" mode and can rebuild often. I am asking for direction and suggestions as to which commits might be at fault. I am sorry that I didn't detect this problem earlier in the release cycle. Hope we can resolve this before 9.2-RELEASE. Thanks. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
