The checksum field in the EEPROM on HPPA is really not a checksum but a signature (0x16d6). So allow 0x16d6 as the matching checksum on HPPA systems.
This issue is present on longterm/stable kernels, I have verified that this patch is applicable back to at least 2.6.32.y kernels. v2- changed ifdef to use CONFIG_PARISC instead of __hppa__ CC: Guy Martin <[email protected]> CC: Rolf Eike Beer <[email protected]> CC: Matt Turner <[email protected]> Reported-by: Mikulas Patocka <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]> Acked-by: Jesse Brandeburg <[email protected]> --- drivers/net/e1000/e1000_hw.c | 6 ++++++ 1 files changed, 6 insertions(+), 0 deletions(-) diff --git a/drivers/net/e1000/e1000_hw.c b/drivers/net/e1000/e1000_hw.c index 8545c7a..a5a89ec 100644 --- a/drivers/net/e1000/e1000_hw.c +++ b/drivers/net/e1000/e1000_hw.c @@ -4026,6 +4026,12 @@ s32 e1000_validate_eeprom_checksum(struct e1000_hw *hw) checksum += eeprom_data; } +#ifdef CONFIG_PARISC + /* This is a signature and not a checksum on HP c8000 */ + if ((hw->subsystem_vendor_id == 0x103C) && (eeprom_data == 0x16d6)) + return E1000_SUCCESS; + +#endif if (checksum == (u16) EEPROM_SUM) return E1000_SUCCESS; else { -- 1.7.6 _______________________________________________ stable mailing list [email protected] http://linux.kernel.org/mailman/listinfo/stable
