Now at about 5 hours of uptime. I guess I got lucky and my stock .config doesn't trip over any of the issues others are hitting. I did hit *one* problem: Under 2.6.22-rc6-mm1, 'modprobe tpm_tis' did this: [ 10.028000] tpm_tis 00:0f: 1.2 TPM (device-id 0x1001, rev-id 2) [ 10.088000] tpm_tis 00:0f: Unable to request irq: 8 for probe and the modprobe returned immediately. Under 23-rc1-mm1, the modprobe takes a *long* time: [ 23.787331] tpm_tis 00:0f: 1.2 TPM (device-id 0x1001, rev-id 2) [ 23.787353] tpm0 (IRQ 3) handled a spurious interrupt [ 143.803891] tpm_tis 00:0f: tpm_transmit: tpm_send: error -62 [ 143.803920] tpm0 (IRQ 3) handled a spurious interrupt [ 263.736163] tpm_tis 00:0f: tpm_transmit: tpm_send: error -62 [ 383.668381] tpm_tis 00:0f: tpm_transmit: tpm_send: error -62 [ 385.667261] tpm_tis 00:0f: tpm_transmit: tpm_send: error -62 then it finally returns. I snuck in a few 'echo t > /proc/sysrq_trigger', and it's always waiting here: [ 193.154317] modprobe S 0000001eeae8252d 5488 1446 1 [ 193.154321] ffff8100043d7a98 0000000000000082 0000000000000000 ffffffff80795480 [ 193.154325] ffff8100043d7a48 ffff810003538000 ffffffff806813e0 ffff810003538290 [ 193.154329] 0000000004173800 0000000000000202 00000000000000ff ffffffff8023ba74 [ 193.154332] Call Trace: [ 193.154336] [<ffffffff8023ba74>] __mod_timer+0xc4/0xd6 [ 193.154340] [<ffffffff805273cc>] schedule_timeout+0x8d/0xb4 [ 193.154344] [<ffffffff8023b7be>] process_timeout+0x0/0xb [ 193.154347] [<ffffffff805273c7>] schedule_timeout+0x88/0xb4 [ 193.154353] [<ffffffff880b328a>] :tpm_tis:wait_for_stat+0xb0/0x11a [ 193.154356] [<ffffffff802460ef>] autoremove_wake_function+0x0/0x38 [ 193.154360] [<ffffffff880b31b0>] :tpm_tis:get_burstcount+0x63/0x8d [ 193.154365] [<ffffffff880b367e>] :tpm_tis:tpm_tis_send+0x191/0x1d3 [ 193.154370] [<ffffffff803ba945>] tpm_transmit+0x98/0x1f1 [ 193.154374] [<ffffffff803baaf2>] transmit_cmd+0x14/0x2e [ 193.154377] [<ffffffff803badd8>] tpm_get_timeouts+0xe9/0x13c [ 193.154382] [<ffffffff880b3ac5>] :tpm_tis:tpm_tis_init+0x405/0x44c [ 193.154387] [<ffffffff880b3b3a>] :tpm_tis:tpm_tis_pnp_init+0x2e/0x30 [ 193.154391] [<ffffffff8039d8fc>] pnp_device_probe+0x7b/0xa3 [ 193.154394] [<ffffffff803c691e>] driver_probe_device+0xfa/0x17e [ 193.154397] [<ffffffff803c6a4d>] __driver_attach+0x0/0x94 [ 193.154400] [<ffffffff803c6aa8>] __driver_attach+0x5b/0x94 [ 193.154403] [<ffffffff803c5cd8>] bus_for_each_dev+0x49/0x7a [ 193.154408] [<ffffffff803c6736>] driver_attach+0x1c/0x1e [ 193.154410] [<ffffffff803c6046>] bus_add_driver+0x86/0x1a9 [ 193.154414] [<ffffffff803c6cb3>] driver_register+0x72/0x76 [ 193.154417] [<ffffffff8039d692>] pnp_register_driver+0x1c/0x1e [ 193.154421] [<ffffffff880b8081>] :tpm_tis:init_tis+0x81/0x89 [ 193.154425] [<ffffffff80251d94>] sys_init_module+0x14db/0x1657 [ 193.154433] [<ffffffff8020bece>] system_call+0x7e/0x83 Here's my /proc/interrupts: CPU0 CPU1 0: 15121156 0 IO-APIC-edge timer 1: 3022 0 IO-APIC-edge i8042 3: 0 0 IO-APIC-edge tpm0 8: 0 0 IO-APIC-edge rtc 9: 2 0 IO-APIC-fasteoi acpi 12: 85 0 IO-APIC-edge i8042 14: 46529 0 IO-APIC-edge libata 15: 94 0 IO-APIC-edge libata 16: 1301032 0 IO-APIC-fasteoi nvidia 17: 148 0 IO-APIC-fasteoi iwl3945 19: 10 0 IO-APIC-fasteoi ohci1394, yenta 20: 9548 0 IO-APIC-fasteoi ehci_hcd:usb1, uhci_hcd:usb2 21: 10544 0 IO-APIC-fasteoi uhci_hcd:usb3, HDA Intel 22: 0 0 IO-APIC-fasteoi uhci_hcd:usb4 23: 0 0 IO-APIC-fasteoi uhci_hcd:usb5 506: 111 68979 PCI-MSI-edge eth0 NMI: 0 0 LOC: 15121050 15120952 ERR: 0 (tpm0 on 3 is new with 23-rc1-mm1. I have *no* idea why 22-rc6-mm1 tried to put it on irq 8. Yes, kernel is currently tainted with nvidia module, but at the time of the traceback listed above, I had not yet even gotten the module built, so the kernel was untainted at that point).
