Strange freeze on IBM T23 and freeze on reboot

[Cedric L'homme]

Hello,

I have some random freeze wich need and hard reboot.
When I reboot, the computer randomly freeze ... A lot of random :/
I tried with acpi=off and lapic, sometimes ok, sometimes not ...
It often block on an IRQ assignement and it's seems that it's a winmodem

What info do you need ?

Latest BIOS and Embedded from http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-57669

The line where it freeze, I can see by removing "quiet splash" in the boot line :

[17.894790] ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 9
[17.894831] ACPI: PCI Interrupt 0000:02:02.1[A] -> Link [LNKC] -> GSI 9 (level, low) -> IRQ 9

3 reboot, all freeze; I remove the PCMCIA card Hercules HWGPCMCIA-54-V2 and I can boot :

lspci give me :
02:02.1 Serial controller: Agere Systems LT WinModem (rev 01)

I tried with all IRQ : can't boot
Impossible to disable the IRQ in the BIOS.
I can boot on windows but if I access to the winmodem by "Talk to the modem" : freeze :/
Can't boot on live 5.10, 6.06, 6.10 and 7.04.

Oh ! I boot on recovery mode : 1 time today on 100 try ... Why this time ??????? I don't know :/

Tried with pci=noacpi, noacpi, noapic, nolapic also :)

I was just having a very similar problem with my T23. On a hunch I removed the MiniPCI card which contains the ethernet and modem devices, and I was able to boot again. Putting the card back in caused the boot to freeze again, so it looks like my ethernet/modem card is shot :(

Removing the MiniPCI card is pretty straightforward, but refer to the manual if you get stuck: http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-4UYM3F

Yep, I removed the card and now I can boot :/
Strange ... No clue on thinkwiki or other websites ...
Thanks !
