Re: Kernel hang r247079 mps/vfs/zfs?
Hi, I was testing a patch on r246300 or so, and wanted to see if it would apply cleanly to a newer copy of HEAD. Well it did, except I had a hang at boot, shortly after ZFS version and the last scsi devices appear. This easily could have been related to the patch I was testing, so I wiped /usr/src/ and /usr/obj (after booting kernel.old) and rebuilt world and kernel cleanly. I assumed that would resolve the issue, but it did not. The hang happens right after zfs is announced, and the last da devices (some of which are usb) are reported. It comes before the noisy output of mps. Hang is complete, and single user or verbose don't yield much. I'm having trouble exfiltrating a dmesg from it, but it may be unrelated to the userland issues reported earlier, as single user does not resolve it for me. The svn up was at 11:20 pacific (GMT +8). Anyone else seeing similar issues? Hardware is an LSI mps device, 9210 crossflashed m1015. Pool is a zfs mirror. Works fine booting from r246300 kernel. Motherboard is an AMD Tyan. Pulling USB headers off the board didn't resolve it. I am experiencing a similar hang when updating from r246190 to r247017 on my all zfs system. The system has two drives in a zfs mirror and hangs after detecting the hard drives. The last thing seen is the ada1: Previously was known as ad8 message, then it hangs completely, unable to even ctrl-alt-del or even get the numlock key to toggle the light. System is: CPU: AMD Phenom(tm) II X4 955 Processor (3214.39-MHz K8-class CPU) with ASUS M4A78LT-M board. Let me know if other details will help.

Steve Symptoms are identical to mine as far as I can tell. I did see fatal trap flash in one case, but couldn't read the crash info. It doesn't always just hang, once I got fatal trap and a reboot, other times I got a hard reboot without fatal trap printout. Unfortunately I wasn't able to catch anything other than fatal trap... before the machine cycled.
