| Priority: | Minor | Regression? | No |
| Status: | Closed/Complete | Components: | wcb4xxp |
| Versions: | 2.6.1 | Frequency of Occurrence | Frequent |
| Related Issues: | |||
| Environment: | CentOS 6.3, kernel 2.6.32-279.el6.x86_64, Digium B410P | Attachments: | ( 0) messages.txt |
| Description: | When wcb4xxp is loaded with debug st state bit set (e.g. module option debug=32) kernel oopses appear from time to time, see attached [^messages.txt].
Changing the kmalloc() flag _GFP_KERNEL_ to _GFP_ATOMIC_ in function _hfc_decode_st_state()_ seems to make the oopses disappear. | ||
