This commit has broken mips32 on my 128MB RAM routerstation pro board. I've tested the commit before this one (and it works). I've also tested today's -HEAD as there was some subsequent fixes to the sfbuf code. It hasn't completely fixed things - I still see processes throwing VM errors: umass0:0:0: Attached to scbus0 Trying to mount root from ufs:redboot/rootfs.uzip []... warning: no time-of-day clock registered, system time will not be set accurately da0 at umass-sim0 bus 0 scbus0 target 0 lun 0 da0: Removable Direct Access SCSI-0 device da0: Serial Number 000000009451 da0: 40.000MB/s transfers da0: 3902MB (7991296 512 byte sectors: 255H 63S/T 497C) da0: quirks=0x3 Aug 28 08:07:57 init: login_getclass: unknown class 'daemon' BAD_PAGE_FAULT: pid 27 tid 100045 (mount), uid 0: pc 0x40514dd0 got a read fault (type 0x2) at 0x4040011c Trapframe Register Dump: zero: 0 at: 0x7fffffff v0: 0 v1: 0x404000fc a0: 0x54 a1: 0x40400000 a2: 0 a3: 0x1 t0: 0 t1: 0x40c0300c t2: 0x40800168 t3: 0x2f t4: 0x40c00030 t5: 0 t6: 0x748 t7: 0x402c70 t8: 0x13 t9: 0x40514d58 s0: 0x3 s1: 0x40418798 s2: 0 s3: 0x404ec4 s4: 0x40418798 s5: 0x40418798 s6: 0 s7: 0 k0: 0 k1: 0 gp: 0x405ec910 sp: 0x7ffee348 s8: 0 ra: 0x4051534c sr: 0xfc13 mullo: 0x6719 mulhi: 0xc badvaddr: 0x4040011c cause: 0x8 pc: 0x40514dd0 Page table info for pc address 0x40514dd0: pde = 0x813da000, pte = 0xa00569da Dumping 4 words starting at pc address 0x40514dd0: 8c700020 32030ff0 00032102 240300ff Page table info for bad address 0x4040011c: pde = 0x813da000, pte = 0 pid 27 (mount), uid 0: exited on signal 11 *** Populating /var .. .. so how can we debug what's going on? -- You are receiving this mail because: You are the assignee for the bug.
