I don't know whether to blame a recent update to debian testing from stable --- likely it would be a glibc issue, but... I did run into the _syscall0() problem after that, and I found that I could get around it by appropriately #define _KERNEL prior to #include <linux/unistd.h>. What I don't get about the remark of Paolo is that _syscall0() is a userland thing, not a kernel thing.
I.e. any user program should be able to use _syscall() to get an open coded call to the kernel. Anyway, my problem: 2.6.15, 2.6.17.13 (both patched as above), and 2.6.19-rc3 all fail during ifup -a: + echo -n 'Configuring network interfaces: ' Configuring network interfaces: + ifup -a BUG: soft lockup detected on CPU#0! 083bf9f0: [<080632a2>] dump_stack+0x22/0x30 083bfa08: [<080a25c4>] softlockup_tick+0x84/0xa0 083bfa20: [<0808ca32>] run_local_timers+0x12/0x20 083bfa28: [<0808c796>] update_process_times+0x36/0x90 083bfa48: [<080636fc>] timer_handler+0x3c/0x70 083bfa64: [<080798f9>] sig_handler_common_skas+0xa9/0x100 083bfa88: [<08075413>] real_alarm_handler+0x23/0x60 083bfaa0: [<080754a2>] alarm_handler+0x52/0x70 083bfabc: [<08077eda>] hard_handler+0x1a/0x20 083bfacc: [<ffffe420>] _etext+0xf7df5404/0x0 083bfe14: [<081a3431>] inet_ioctl+0x61/0xa0 083bfe2c: [<081525a4>] sock_ioctl+0x144/0x2b0 083bfe60: [<080d022f>] do_ioctl+0x5f/0x70 083bfe80: [<080d04e2>] vfs_ioctl+0x62/0x2d0 083bfebc: [<080d0791>] sys_ioctl+0x41/0x70 083bfee4: [<08065a83>] handle_syscall+0xd3/0xe0 083bff54: [<0807897a>] handle_trap+0x2a/0x130 083bff7c: [<08079074>] userspace+0x1c4/0x220 083bffd4: [<0806569e>] fork_handler+0x9e/0xb0 083bfffc: [<00000000>] _sinittext+0xf7fb7000/0x20 If I boot with "linux emergency" login to the single user shell and run "ifup -a", everything is fine.
