I've got it, but I had a problem: I filled the dmesg buffer. I will try to find where to enlarge it. I have posted the partial result to: http://www.dea.icai.upcomillas.es/romano/linux/info/dmesg-resume-nofreeze.txt in the hope that something can be used. I am running 2.6.21.2, with the "no freeze kthreads at all" patch from Matthew Garrett, with this add-on: --- drivers/base/firmware_class.c.orig 2007-05-30 12:19:59.000000000 +0200 +++ drivers/base/firmware_class.c 2007-05-29 19:39:56.000000000 +0200 @@ -471,7 +471,11 @@ struct device *device) { int uevent = 1; - return _request_firmware(firmware_p, name, device, uevent); + int rval; + printk(KERN_ERR "FW: requesting firmware (sync) for %s\n", name); + rval = _request_firmware(firmware_p, name, device, uevent); + printk(KERN_ERR "FW: return %d\n", rval); + return rval; } /** @@ -545,7 +549,9 @@ struct task_struct *task; struct firmware_work *fw_work = kmalloc(sizeof (struct firmware_work), GFP_ATOMIC); - + + printk(KERN_ERR "FW: requesting firmware (async) for %s\n", name); + if (!fw_work) return -ENOMEM; if (!try_module_get(module)) { @@ -569,8 +575,12 @@ fw_work->cont(NULL, fw_work->context); module_put(fw_work->module); kfree(fw_work); + printk(KERN_ERR "FW: failing return %d\n", PTR_ERR(task)); return PTR_ERR(task); } + + printk(KERN_ERR "FW: normal return\n"); + return 0; } -- Romano Giannetti --- [EMAIL PROTECTED] Sorry for the following disclaimer, it's attached by our otugoing server and I cannot shut it up. -- La presente comunicación tiene carácter confidencial y es para el exclusivo uso del destinatario indicado en la misma.
