Ok - thanks for the dmesg output and log. I suspect you've already tried cycling power on the machine (If not, please do). I have no idea what M$ XP was doing that might "fix" the problem. I was just suspicious of our byte accesses to the same dword. To answer you previous question, it's possible that M$ only uses dword accesses. I don't know. > inlined the log excellent - sounds like you are making forward progress even if we can not reproduce the problem...worst case other users (or customers) have a "work around" :^/ thanks, grant ps. I'll be unavailable until this weekend when I want to look at the old and new logs a bit more. > > regards, > manu > > > [17181623.040000] gpif status: 6000 irqcfg: 0000 > [17181623.040000] irq: 18, latency: 64 > [17181623.040000] memory: 0xefeff000, mmio: 0xe18f4000 > [17181623.040000] found a UNKNOWN PCI UNKNOWN device on (02:0a.0), > [17181623.040000] Mantis Rev 1 [1822:0031], irq: 18, latency: 64 > [17181623.040000] memory: 0xefeff000, mmio: 0xe18f4000 > [17181623.040000] mantis_i2c_write: Address=[0x50] <W>[ 08 ] > [17181623.040000] mantis_i2c_read: Address=[0x50] <R>[ 00 00 > 00 00 00 00 ] > [17181623.044000] MAC Address=[00:00:00:00:00:00] > [17181623.044000] mantis_alloc_buffers (0): DMA=0x186b0000 > cpu=0xd86b0000 size=65536 > [17181623.044000] mantis_alloc_buffers (0): RISC=0x1c3af000 > cpu=0xdc3af000 size=1000 > [17181623.044000] DVB: registering new adapter (Mantis dvb adapter). > [17181623.564000] mantis_frontend_init (0): Probing for STB0899 > (DVB-S/DSS/DVB-S2) > [17181623.564000] stb0899_write_regs [0xf1b6]: 02 > [17181623.564000] mantis_i2c_write: Address=[0x68] <W>[ f1 b6 02 ] > [17181623.564000] stb0899_write_regs [0xf1c2]: 00 > [17181623.564000] mantis_i2c_write: Address=[0x68] <W>[ f1 c2 00 ] > [17181623.568000] stb0899_write_regs [0xf1c3]: 00 > [17181623.568000] mantis_i2c_write: Address=[0x68] <W>[ f1 c3 00 ] > [17181623.568000] mantis_i2c_write: Address=[0x68] <W>[ f0 00 ] > [17181623.568000] mantis_i2c_read: Address=[0x68] <R>[ 82 ] > [17181623.568000] stb0899_read_reg: Reg=[0xf000], data=82 > [17181623.568000] stb0899_get_dev_id: Device ID=[8], Release=[2] > [17181623.568000] mantis_i2c_write: Address=[0x68] <W>[ f3 fc > 00 04 00 00 ] > [17181623.572000] mantis_i2c_write: Address=[0x68] <W>[ f3 34 ] > [17181623.572000] mantis_i2c_read: Address=[0x68] <R>[ 31 44 4d 44 > ] > [17181623.572000] mantis_i2c_write: Address=[0x68] <W>[ f3 34 ] > [17181623.572000] mantis_i2c_read: Address=[0x68] <R>[ 31 44 4d 44 > ] > [17181623.576000] stb0899_read_s2reg Device=[0xf3fc], Base > address=[0x00000400], Offset=[0xf334], Data=[0x444d4431] > [17181623.576000] mantis_i2c_write: Address=[0x68] <W>[ f3 fc > 00 04 00 00 ] > [17181623.576000] mantis_i2c_write: Address=[0x68] <W>[ f3 00 ] > [17181623.576000] mantis_i2c_read: Address=[0x68] <R>[ 01 00 00 00 > ] > [17181623.580000] mantis_i2c_write: Address=[0x68] <W>[ f3 3c ] > [17181623.580000] mantis_i2c_read: Address=[0x68] <R>[ 01 00 00 00 > ] > [17181623.580000] stb0899_read_s2reg Device=[0xf3fc], Base > address=[0x00000400], Offset=[0xf33c], Data=[0x00000001] > [17181623.580000] stb0899_get_dev_id: Demodulator Core ID=[DMD1], > Version=[1] > [17181623.580000] mantis_i2c_write: Address=[0x68] <W>[ fa fc > 00 08 00 00 ] > [17181623.584000] mantis_i2c_write: Address=[0x68] <W>[ fa 00 ] > [17181623.584000] mantis_i2c_read: Address=[0x68] <R>[ 4c 00 00 00 > ] > [17181623.588000] mantis_i2c_write: Address=[0x68] <W>[ fa 2c ] > [17181623.588000] mantis_i2c_read: Address=[0x68] <R>[ 31 43 45 46 > ] > [17181623.588000] stb0899_read_s2reg Device=[0xfafc], Base > address=[0x00000800], Offset=[0xfa2c], Data=[0x46454331] > [17181623.588000] mantis_i2c_write: Address=[0x68] <W>[ fa fc > 00 08 00 00 ] > [17181623.592000] mantis_i2c_write: Address=[0x68] <W>[ fa 34 ] > [17181623.592000] mantis_i2c_read: Address=[0x68] <R>[ 01 00 00 00 > ] > [17181623.592000] mantis_i2c_write: Address=[0x68] <W>[ fa 34 ] > [17181623.592000] mantis_i2c_read: Address=[0x68] <R>[ 01 00 00 00 > ] > [17181623.596000] stb0899_read_s2reg Device=[0xfafc], Base > address=[0x00000800], Offset=[0xfa34], Data=[0x00000001] > [17181623.596000] stb0899_get_dev_id: FEC Core ID=[FEC1], Version=[1] > [17181623.596000] stb0899_attach: Attaching STB0899 > [17181623.596000] mantis_frontend_init (0): found STB0899 > DVB-S/DSS/DVB-S2 frontend @0x68 > [17181623.596000] mantis_frontend_init (0): Probing for STB6100 tuner > [17181623.596000] stb6100_attach: Attaching > [17181623.596000] mantis_frontend_init (0): found STB6100 tuner @0x60 > [17181623.596000] mantis_frontend_init (0): Probing for LNBP21 SEC > [17181623.596000] mantis_i2c_write: Address=[0x08] <W>[ 40 ] > [17181623.596000] DVB: registering frontend 0 (STB0899 Multistandard)... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
