Hi Manu, the changeset 7344 3ae5e8d85a55 crashes after doing "modprobe mantis" and the computer hangs. I could still log in from remote, doing an "init 6", but the machine did not reboot anymore. So I had to push the "Reset". Below is /var/log/messges May 23 23:10:51 linux-sh8m kernel: ACPI: PCI Interrupt 0000:02:01.0[A] -> GSI 21 (level, low) -> IRQ 21 May 23 23:10:51 linux-sh8m kernel: irq: 21, latency: 64 May 23 23:10:51 linux-sh8m kernel: memory: 0xdfeff000, mmio: 0xffffc200006f6000 May 23 23:10:51 linux-sh8m kernel: found a VP-2033 PCI DVB-C device on (02:01.0), May 23 23:10:51 linux-sh8m kernel: Mantis Rev 1 [1822:0008], irq: 21, latency: 64 May 23 23:10:51 linux-sh8m kernel: memory: 0xdfeff000, mmio: 0xffffc200006f6000 May 23 23:10:51 linux-sh8m kernel: MAC Address=[00:08:ca:19:e9:b6] May 23 23:10:51 linux-sh8m kernel: mantis_alloc_buffers (0): DMA=0x69b90000 cpu=0xffff810069b90000 size=65536 May 23 23:10:51 linux-sh8m kernel: mantis_alloc_buffers (0): RISC=0x5afe0000 cpu=0xffff81005afe0000 size=1000 May 23 23:10:51 linux-sh8m kernel: DVB: registering new adapter (Mantis dvb adapter) May 23 23:10:52 linux-sh8m kernel: mantis_frontend_init (0): Probing for CU1216 (DVB-C) May 23 23:10:52 linux-sh8m kernel: TDA10021: i2c-addr = 0x0c, id = 0x7c May 23 23:10:52 linux-sh8m kernel: mantis_frontend_init (0): found Philips CU1216 DVB-C frontend (TDA10021) @ 0x0c May 23 23:10:52 linux-sh8m kernel: mantis_frontend_init (0): Mantis DVB-C Philips CU1216 frontend attach success May 23 23:10:52 linux-sh8m kernel: DVB: registering frontend 0 (Philips TDA10021 DVB-C)...
