FYI, you should probably enable CONFIG_MODE_SKAS - it now (since 2.6.13) works even on unpatched hosts, in SKAS0 mode (even if it's a bit slower than SKAS3). The only reason TT mode is still in is that its code is useful for debugging and future extension (i.e. there's no SMP support in SKAS0/3 modes). Please report whether problems arise even in SKAS0 mode. > tracing thread pid = 32600 > Linux version 2.6.16-rc1-git4 ([EMAIL PROTECTED]) (gcc version 3.3.6 > (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8)) #1 Wed Jan 25 11:07:25 EET > 2006 > Built 1 zonelists > Kernel command line: ubd0=/home/penberg/virtualized/Debian-3.0r2.ext2 > root=98:0 PID hash table entries: 256 (order: 8, 4096 bytes) > Dentry cache hash table entries: 8192 (order: 3, 32768 bytes) > Inode-cache hash table entries: 4096 (order: 2, 16384 bytes) > Memory: 29388k available > Mount-cache hash table entries: 512 > Checking for host processor cmov support...Yes > Checking for host processor xmm support...No > Checking that host ptys support output SIGIO...Yes > Checking that host ptys support SIGIO on close...No, enabling workaround > Checking for /dev/anon on the host...Not available (open failed with errno > 2) Disabling 2.6 AIO in tt mode > 2.6 host AIO support not used - falling back to I/O thread > NET: Registered protocol family 16 > mconsole (version 2) initialized on /home/penberg/.uml/Z81xOu/mconsole > ubd: Synchronous mode > VFS: Disk quotas dquot_6.5.1 > Dquot-cache hash table entries: 1024 (order 0, 4096 bytes) > io scheduler noop registered > io scheduler anticipatory registered > io scheduler deadline registered > io scheduler cfq registered > NET: Registered protocol family 2 > IP route cache hash table entries: 512 (order: -1, 2048 bytes) > TCP established hash table entries: 2048 (order: 1, 8192 bytes) > TCP bind hash table entries: 2048 (order: 1, 8192 bytes) > TCP: Hash tables configured (established 2048 bind 2048) > TCP reno registered > TCP bic registered > NET: Registered protocol family 1 > NET: Registered protocol family 17 > Initialized stdio console driver > Console initialized on /dev/tty0 > Initializing software serial port version 1 > ubda: unknown partition table > VFS: Mounted root (ext2 filesystem) readonly. > line_ioctl: tty0: ioctl KDSIGACCEPT called > os_set_fd_async : failed to set O_ASYNC and O_NONBLOCK on fd # 6, errno = 9 > register_winch_irq - failed to register IRQ > os_set_fd_async : failed to set O_ASYNC and O_NONBLOCK on fd # 6, errno = 9 > register_winch_irq - failed to register IRQ > INIT: os_set_fd_async : failed to set O_ASYNC and O_NONBLOCK on fd # > 6, errno = 9 > register_winch_irq - failed to register IRQ > version 2.84 bootingos_set_fd_async : failed to set O_ASYNC and > O_NONBLOCK on fd # 6, errno = 9 > register_winch_irq - failed to register IRQ > > Kernel panic - not syncing: read of switch_pipe failed, errno = 11 > > EIP: 0073:[<400b6e17>] CPU: 0 Not tainted ESP: 007b:9fe4a090 EFLAGS: > 00200282 Not tainted > EAX: 00000271 EBX: 9fe4a25c ECX: 0000540e EDX: 9fe4a25c > ESI: 00000000 EDI: 00000000 EBP: 9fe4a35c DS: 007b ES: 007b > a0bc3b74: [<a0021de7>] show_regs+0xdf/0xe1 > a0bc3ba0: [<a0010521>] panic_exit+0x25/0x3f > a0bc3bb0: [<a0033393>] notifier_call_chain+0x1c/0x3c > a0bc3bd0: [<a0025bd2>] panic+0x4b/0xd3 > a0bc3be8: [<a0010ca2>] switch_to_tt+0xc2/0x129 > a0bc3c1c: [<a000d0c2>] _switch_to+0x39/0xbe > a0bc3c50: [<a015d319>] schedule+0x41f/0x4a0 > a0bc3cb8: [<a000d163>] interrupt_end+0x1c/0x3a > a0bc3cc8: [<a0012167>] sig_handler_common_tt+0xd3/0x100 > a0bc3d04: [<a001de03>] sig_handler+0x2f/0x3c > a0bc3d1c: [<ffffe420>] _etext+0x5fe9ea61/0x0 > > sleeping process 1392 got unexpected signal : 10 > remove_umid_dir - actually_do_remove failed with err = -2 > remove_umid_dir - actually_do_remove failed with err = -2 -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
