This kernel is configured with very small kmsg buffer... I could only capture the last portion of the commands: ``` pcmcia_read_cis_mem(1, 0xe3, 2) 0x80 0x09 0x00 0x00 ... pcmcia_read_cis_mem(1, 0xee, 2) 0xff 0xff 0x00 0x00 ... pcmcia_read_cis_mem(0, 0x0, 5) 0x00 0x00 0x00 0x00 ... pcmcia_read_cis_mem(0, 0x0, 5) 0x00 0x00 0x00 0x00 ... pcmcia 0.0: pcmcia: registering new device pcmcia0.0 (IRQ: 217) pcmcia_read_cis_mem(1, 0x4d, 2) 0x06 0x00 0x48 0x04 // is that FUNCID and MANUFID? pcmcia_read_cis_mem(1, 0x12, 30) 0x08 0x00 0x53 0x75 ... pcmcia_read_cis_mem(1, 0xb1, 5) 0x01 0x01 0x00 0x07 ... pcmcia_write_cis_mem(1, 0x383, 1) pcmcia_write_cis_mem(1, 0x380, 1) <systemd-journald warning that /dev/kmsg is overrun...> pcmcia_write_cis_mem(1, 0x381, 1) pcmcia_write_cis_mem(1, 0x397, 1) pcmcia_write_cis_mem(1, 0x398, 1) pcmcia_write_cis_mem(1, 0x399, 1) pcmcia_read_cis_mem(1, 0x397, 1) !! attempt to read CIS mem at addr 0x397 (CISTPL_MAX_CIS_SIZE is 0x200) return -1; ``` Not knowing what's what here, at least I see there's some inconsistency. - write is okay but read fails on bound check - the ssb offsets are u8 and values like 0x397 are (pcmcia base + offset), but the bound check is not aware of the base address, right?
