Hi, I am seeing period occurances of the same system call with the same WITNESS warning and similar backtrace on yesterday's AMD64 CURRENT. ---------------------- ral0: link state changed to DOWN malloc(M_WAITOK) of "32", forcing M_NOWAIT with the following non-sleepable locks held: exclusive sleep mutex ral0 (network driver) r =3D 0 (0xffffffff80c64de8) locked @ /usr/src/sys/dev/ral/if_ral.c:2167 KDB: stack backtrace: kdb_backtrace() at kdb_backtrace+0x37 witness_warn() at witness_warn+0x2c1 uma_zalloc_arg() at uma_zalloc_arg+0x69 malloc() at malloc+0xf5 ieee80211_ioctl_setoptie() at ieee80211_ioctl_setoptie+0x4b ieee80211_ioctl_set80211() at ieee80211_ioctl_set80211+0x64e ieee80211_ioctl() at ieee80211_ioctl+0x125 ral_ioctl() at ral_ioctl+0xa4 in_control() at in_control+0xc2f ifioctl() at ifioctl+0x1f6 soo_ioctl() at soo_ioctl+0x38c ioctl() at ioctl+0x476 syscall() at syscall+0x332 Xfast_syscall() at Xfast_syscall+0xa8 --- syscall (54, FreeBSD ELF64, ioctl), rip =3D 0x8007c2d4c, rsp =3D 0x7fffffffdfd8, rbp =3D 0x18 --- ral0: link state changed to UP ---------------------- I am indeed curious to understand what exactly is causing these WITNESS war= nings Regards, Pascal Hofstee
