Sure, happens here on amd64, Hollow has it on i386. I myself use
2.6.10-rc3-vs1.9.3.11:
# vsched --xid 49161 --fill-rate 2 --interval 100 --tokens 499 --tokens-min 1
--tokens-max 999 --prio-bias 0
Segmentation fault
# vsched --xid 49161 --fill-rate 2 --interval 100 --tokens 499 --tokens-min 1
--tokens-max 999 --prio-bias 0 -- true
#
Both methods set the values correctly according to '# cat
/proc/virtual/49161/sched'
I attach an strace of the failed call:
# strace vsched --xid 49161 --fill-rate 2 --interval 100 --tokens 499
--tokens-min 1 --tokens-max 999 --prio-bias 0
