i just updated my gcc from 2.96 to 3.0.1 and now i cant compile kernel 2.4.9 anymore, make bzImage fails with the following error message:

acct.c: In function `check_free_space':
acct.c:147: Unrecognizable insn:
(insn 335 102 336 (parallel[

            (set (reg/v:SI 2 ecx [44])
                (const_int 0 [0x0]))
            (clobber (reg:CC 17 flags))
        ] ) -1 (insn_list:REG_DEP_ANTI 100 (insn_list:REG_DEP_ANTI 102

(nil)))

(nil)))

can anyone tell me how to fix this?

Use gcc 2.96 or gcc 3.0.0. You broke the compiler. Please also see the gcc bug reporting instructions. You will actually make a gcc hacker very happy reporting that problem.

Except that a similar problem with capi existed allready with gcc 3.0 + kernels 2.4.*, and that problem was reported to gcc people multiple times. But it is still broken in gcc 3.0.1:

bp2.c:414: warning: sbp2_host_info_lock' defined but not used capi.c: In function capi_ioctl':
capi.c:1031: Unrecognizable insn:
(insn/i 1675 3103 3100 (parallel[ capi.c:1031: Internal error: Segmentation fault Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

So, does anyone have any ideas? That problem is critical because it makes ISDN (capi 2) unusable with kernels 2.4.* + gcc 3.0.*

All other things seem to function pretty well with 2.4.9 + 3.0.1.

I get the same sort of Unrecognizable insn: error in signal.c with my setup. This is true today with the latest cvs gcc.
