Sad: 3.1.15 fatal crash (Toshiba laptop w Xircom CBEII-10/100)

Context: laptop Toshiba Satellite Pro 4270 running kernel 2.2.15, pcmcia 3.1.15 with a Xircom CBEII-10/100 Cardbus card. I was running succesfully a pre 3.1.15 version (~ May 15) of the PCMCIA drivers. It was usable but I have to make some manipulations to get it started after each reboot (else, the interface was up but no way to pass a single packet). I've decided to upgrade to 3.1.15 today but now, the system crashes systematically while loading the module i82365.o (no way to recover, not even with magic sysReq). I've also tried pre-3.1.16 (01-Jun-00) but it is the same thing. Strangely, I'm able to start the pcmcia service while in "single user" mode.. but I'm unable to pass a single packet :( Unfortunatly, I've overwrited my pre-3.1.15 copy (with final 3.1.15) and it's no longer available on the ftp site so I'm not able to downgrade :(( Here is the lspci output (bridge, cardbus briges, xircom card [from the single user boot]) : 00:05.3 Bridge: Intel Corporation 82371AB PIIX4 ACPI (rev 03) 00:0b.0 CardBus bridge: Toshiba America Info Systems ToPIC95 PCI to Cardbus Bridge with ZV Support (rev 20) 00:0b.1 CardBus bridge: Toshiba America Info Systems ToPIC95 PCI to Cardbus Bridge with ZV Support (rev 20) 10:00.0 Ethernet controller: Xircom Cardbus Ethernet 10/100 (rev 03). When it is working, here is the output of 'insmod i82365.o' : Intel PCIC probe: Toshiba ToPIC100 rev 20 PCI-to-CardBus at slot 00:0b, mem 0x68000000 host opts [0]: [slot 0xf0] [ccr Ox10] [cdr 0x86] [rcr 0xc000000] [pci irq 11] [lat 64/176] [bus 20/20] host opts [1]: [slot 0xf0] [ccr Ox20] [cdr 0x86] [rcr 0xc000000] [pci irq 11] [lat 64/176] [bus 21/21] ISA irqs (default) = 4,5,7,9,10,12 PCI status changes Else, no output [ even with PCMCIA_DEBUG=1 ] As it crashes even when the slots are all empty, I don't think this is a Xircom problem. Any idea ?

> > When it is working, here is the output of 'insmod i82365.o' : So are these messages from the pre-3.1.15 drivers, or the 3.1.15 drivers booted in single user mode? (it would be useful to compare those two cases) Looking at the changes in 3.1.15, I'm not seeing any good candidates for where the bug might be. I assume you did not change anything else around the time you tried to upgrade to 3.1.15? (no kernel changes? no changes in how other devices are configured?) The PCMCIA-HOWTO has some hints for debugging system lockups that might be helpful. There are also some suggestions in the chapter on diagnosing configuration problems. -- Dave
