It is not vanilla kernel. squashfs is not merged mainline yet. > Unhandled kernel unaligned access[#1]: > Cpu 0 > $ 0 : 00000000 10008400 69725020 94001b90 > $ 4 : 94003200 7265746e 00000002 00000000 > $ 8 : 94016338 940162b0 94016228 940161a0 > $12 : 94e5653c 943a0000 943a0000 94e5659c > $16 : 94001b80 00000000 94003200 00000002 > $20 : 00000000 00000000 00000000 00000000 > $24 : 00000000 9410b8a0 > $28 : 943e4000 943e5ec0 00000000 94175e40 > Hi : 00000003 > Lo : 00000002 > epc : 941742bc drain_freelist+0x6c/0xf8 Not tainted > ra : 94175e40 cache_reap+0xc0/0x124 > Status: 10008402 KERNEL EXL > Cause : 10800010 > BadVA : 7265746e > PrId : 00018448 ... > 0xffffffff941742bc <drain_freelist+108>: lw v1,0(a1) The value of a1 (0x7265746e) is not a kernel address and I do not think drain_freelist use such an address.
