>Description:
When trying to boot an 8.2-RELEASE kernel, mfi(4) enters an infinite command timeout loop.
With MFI_DEBUG I get the following output:
mfi0: COMMAND 0xffffff80002c6440 TIMEOUT AFTER 59 SECONDS
mfi0: cm=0xffffff80002c6440 index=8 total_frame_size=52 extra_frames=0
mfi0: flags=83<MAPPED,DATAIN,Q_BUSY>
mfi0: cmd=MFI_CMD_DCMD opcode=LD_GET_LIST data_len=1032
mfi0: flags=12<SGL64,READ>
SG List:
0x1a3d000:001032
mfi0: mfi_timeout 2522 COMMAND 0xffffff80002c6440 S/G count bad 0 1032 1032
0x1a3d000
mfi0: cm=0xffffff80002c6440 index=8 total_frame_size=52 extra_frames=0
mfi0: flags=83<MAPPED,DATAIN,Q_BUSY>
mfi0: cmd=MFI_CMD_DCMD opcode=LD_GET_LIST data_len=1032
mfi0: flags=12<SGL64,READ>
SG List:
0x1a3d000:001032
This output repeats itself every 30 seconds (with the timeout counter increasing).
This exact system does not have any problems with 8.1-RELEASE.
The card is an LSI MegaRAID SAS 8408E:
blee@genesis ~ $ pciconf -lv | grep -A4 mfi0
mfi0@pci0:6:14:0: class=0x010400 card=0x10011000 chip=0x04111000 rev=0x00 hdr=0x00
vendor = 'LSI Logic (Was: Symbios Logic, NCR)'
device = 'MegaRAID Family RAID Controller'
class = mass storage
subclass = RAID
blee@genesis ~ $ sudo mfiutil show adapter

>How-To-Repeat:
1) Boot 8.1-RELEASE kernel. Observe no problems.
2) Boot 8.2-RELEASE kernel. Kernel will not boot due to command timeout loop in mfi(4).
