Re: SPL NOT ZERO ON SYSCALL ENTRY

I just managed to trigger such a problem again.
CPU1 hit the breakpoint I planted
after the "SPL NOT LOWERED ON SYSCALL EXIT" in Xsyscall().
CPU0 was in Xtrap0e (which might be inaccurate).
And again:
(gdb) print cpu_info_primary.ci_next->ci_istate
$2 = {ipending = 0x40000000, ilevel = 0x7}

I've got a coredump and a kernel with debug info. Is there
anything I could do to help?

best regards
Matthias
