I have compiled 2.6.33-2, and the same thing happens. That is, modprobe sata_sil24 prints one message to the console suggesting the PCI slot, then freezes the system. Unfortunately it doesn't seem to have managed to write anything to messages/kernel.log, which is on a p-ata disk. I managed to hand copy some of the output from alt-sysrq-t which looks like it includes the stack running as a result of the modprobe -- does this help to explain where the problem is? This was manually copied, so there might be a typo or two: c03118f8 ? schedule+0x897/0x94e c014406a ? ktime_get_ts+0xd7/0xdf c0217b42 ? cfq_rb_erase+0x1b/0x2a c021f449 ? number+0x149/0x20e c023a9cb ? vgacon_scroll+0x180/0x19a c0194e0c ? __insert_vmap_area+0x5e/0x96 c017fac3 ? __alloc_pages_nodemask+0xe2/0x4ec c019b409 ? cache_alloc_refill+0x63/0x417 c02995c9 ? pci_conf1_write+0xb2/0xc0 c029a9fb ? raw_pci_write+0x4e/0x56 c029aa40 ? pci_write+0x1c/0x21 c0228a3e ? pci_bus_write_config_dword+0x46/0x50 c022ae0c ? pcie_set_readrq+0x8c/0x9e f9f185bc ? sil24_init_one+0x1ax/0x21a [sata_sil24] c022d899 ? local_pci_probe+0xb/0xc c022de7d ? pci_device_probe+0x41/0x63 c0287489 ? driver_probe_device+0x76/0xfe c0287451 ? __driver_attach+0x40/0x5b c0286dcd ? bus_for_each_dev0x37/0x5f c0287270 ? driver_attach+0x11/0x13 c0287411 ? __driver_attach+0x0/0x5b c0286852 ? bus_add_driver+0xd6/0x201 c028766b ? driver_register+0x87/0xe0 c022e050 ? __pci_register_driver+0x33/0x89 f9f1d000 ? sil24_init+0x0/0x14 [sata_sil24] c010112d ? do_one_initcall+0x44/0x120 c014f1c2 ? sys_init_module+0xa7/0x1d7 c03130f5 ? syscall_call+0x7/0xb I don't know that it is relevant, but the pcie card is plugged into a pci-pcie converter card. Let me know if there is anything else I can supply to help analyse this (anything I do will have to be in the next couple of days as thats all the time I have to return the goods for a refund!!). -- Richard Mawson Mawson IT Services
