I'll look into this, but it's strange since yesterday I used indeed /proc/sysemu. > # echo 0 > /proc/sysemu > Kernel panic - not syncing: handle_trap - failed to wait at end of > syscall, errno = 0, status = 2943 $ ./testprogs/waitstatus 2943 WSTOPSIG(status) is 11 The signal is: Segmentation fault > EIP: 0073:[<40129e18>] CPU: 0 Not tainted ESP: 007b:bfa14f6c EFLAGS: > 00000246 > Not tainted > EAX: ffffffda EBX: 00000001 ECX: 080e8c08 EDX: 00000002 > ESI: 00000002 EDI: 00000000 EBP: bfa14f90 DS: 007b ES: 007b > 8f4a7c10: [<80048536>] notifier_call_chain+0x1e/0x38 > 8f4a7c30: [<80037ea9>] panic+0x55/0x104 > 8f4a7c50: [<80022163>] handle_trap+0xb3/0x114 > 8f4a7c80: [<800224ce>] userspace+0x176/0x1b0 > 8f4a7cd0: [<80023020>] force_flush_all_skas+0x24/0x28 > 8f4a7cf0: [<80022afd>] fork_handler+0xbd/0xd0 > 8f4a7d00: [<80022ae0>] fork_handler+0xa0/0xd0 > 8f4a7d20: [<8032f638>] __restore+0x0/0x8 > 8f4a7d60: [<8032f891>] kill+0x11/0x20 -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".

It's ancient, and most likely contributes to this issue. Ah, in that case it's known, and was fixed at the host level. /proc/sysemu had been tested, but only on 2.4 hosts, and 2.6 behaviour differed. > > And which SKAS patch (btw, any news on the host SMP crash)? > Yes, I get crashes with this kernel, too.
