Hello,
I have an user report that the auerswald driver is causing a BUG().
Has somebody a hint for me?
Test Sequence:
1) use a plain 2.4.24 Kernel:
Feb 11 16:24:53 gandalf kernel: usb.c: new USB bus registered, assigned bus number 1
Feb 11 16:24:53 gandalf kernel: hub.c: USB hub found
Feb 11 16:24:53 gandalf kernel: hub.c: 3 ports detected
Feb 11 16:24:53 gandalf kernel: PCI: Found IRQ 11 for device 00:01.3
Feb 11 16:24:53 gandalf kernel: PCI: Sharing IRQ 11 with 00:01.2

Feb 11 16:24:53 gandalf kernel: usb.c: new USB bus registered, assigned bus number 2
Feb 11 16:24:53 gandalf kernel: hub.c: USB hub found
Feb 11 16:24:53 gandalf kernel: hub.c: 3 ports detected
2) The auerswald device is detected:
Feb 11 16:34:16 gandalf kernel: hub.c: new USB device 00:01.2-1, assigned address 2
Feb 11 16:34:16 gandalf kernel: usb.c: USB device 2 (vend/prod 0x9bf/0xdb) is not
claimed by any active driver.
Feb 11 16:34:30 gandalf kernel: usb.c: registered new driver auerswald
Feb 11 16:34:30 gandalf kernel: auermain.c: device is a COMpact 4410,Ser# C0C054E, MSN

3) The device is disconnected:
Feb 11 16:34:50 gandalf kernel: usb.c: USB disconnect on device 00:01.2-1 address 2
Feb 11 16:34:50 gandalf kernel: auermain.c: device /dev/usb/auer0 now disconnecting
4) The device is connected again:
Feb 11 16:35:12 gandalf kernel: hub.c: new USB device 00:01.2-1, assigned address 3
Feb 11 16:35:12 gandalf kernel: auermain.c: device is a COMpact 4410,Ser# C0C054E, MSN

10 8b 45 00
The BUG() is triggered when the auerswald driver is trying to
enable an INT input endpoint in auermain.c::auerswald_int_open
The BUG() is in
static inline void *dma_to_ed_td (struct hash_list_t * entry, dma_addr_t dma)
{
struct hash_t * scan = entry->head;
while (scan && scan->dma != dma)
scan = scan->next;
if (!scan)
BUG();
return scan->virt;
}
This type of error is not present in any Suse System I use normally for development.
Can someone give me hint what may cause this problem?
best regards
Wolfgang Mües
